According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

  - An out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in     drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128     (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing     a denial of service(DoS). (CVE-2022-36280)

  - A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card     system resource overload, causing a fail in the intel_gvt_dma_map_guest_page function. This issue could     allow a local user to crash the system. (CVE-2022-3707)

  - An incorrect read request flaw was found in the Infrared Transceiver USB driver in the Linux kernel. This     issue occurs when a user attaches a malicious USB device. A local user could use this flaw to starve the     resources, causing denial of service or potentially crashing the system. (CVE-2022-3903)

  - A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking     configuration (redirecting egress packets to ingress using TC action 'mirred') a local unprivileged user     could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a     retransmission, resulting in a denial of service condition. (CVE-2022-4269)

  - The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176. We recommend upgrading past commit     a664ec9158eeddd75121d39c9a0758016097fa96 (CVE-2023-0045)

  - A deadlock flaw was found in the Linux kernel's BPF subsystem. This flaw allows a local user to     potentially crash the system. (CVE-2023-0160)

  - There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a     use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can     install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this     socket is disconnected and reused as a listener. If a new socket is created from the listener, the context     is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend     upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

  - A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race     problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 ('net: sched: fix race     condition in qdisc_graft()') not applied yet, then kernel could be affected. (CVE-2023-0590)

  - A memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a     user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2023-1073)

  - A memory leak flaw was found in the Linux kernel's Stream Control Transmission Protocol. This issue may     occur when a user starts a malicious networking service and someone connects to this service. This could     allow a local user to starve resources, causing a denial of service. (CVE-2023-1074)

  - A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a     type confusion in their initialization function. While it will be often correct, as tuntap devices require     CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This     would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing     network filters. (CVE-2023-1076)

  - A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the     way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate     their privileges on the system. (CVE-2023-1118)

  - Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege     Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-     after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this     vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git     commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)

  - A data race flaw was found in the Linux kernel, between where con is allocated and con->sock is set. This     issue leads to a NULL pointer dereference when accessing con->sock->sk in net/tipc/topsrv.c in the tipc     protocol in the Linux kernel. (CVE-2023-1382)

  - A remote denial of service vulnerability was found in the Linux kernel's TIPC kernel module. The while     loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue.
    Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system     to instantly spike to 100%, causing a denial of service condition. (CVE-2023-1390)

  - A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some     uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an     information leak. (CVE-2023-1513)

  - A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel.
    This issue may allow a local attacker with user privilege to cause a denial of service. (CVE-2023-1582)

  - A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the     Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from     suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of     the CPU similar to the speculative execution behavior kind of attacks. (CVE-2023-1637)

  - A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in virtio network     subcomponent in the Linux kernel due to a double fget. This flaw could allow a local attacker to crash the     system, and could even lead to a kernel information leak problem. (CVE-2023-1838)

  - In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure     (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)

  - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in     the Linux Kernel. The message from user space is not checked properly before transferring into the device.
    This flaw allows a local user to crash the system or potentially cause a denial of service.
    (CVE-2023-28328)

  - do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

  - An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer     overflow. (CVE-2023-28772)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of kernel installed on the remote host is prior to 4.14.248-129.473. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2021-1539 advisory.

  - Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP     socket with an attached dccps_hc_tx_ccid object as a listener after being released. Fixed in Ubuntu Linux     kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and 3.2.0-149.196.
    (CVE-2020-16119)

  - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass     RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users     with the ability to start and control a VM to read/write random pages of memory and can result in local     privilege escalation. (CVE-2021-22543)

  - In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from     kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store     operation does not necessarily occur before a store operation that has an attacker-controlled value.
    (CVE-2021-35477)

  - .A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse     a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. This race     condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root.
    (CVE-2021-3609)

  - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on     inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

  - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was     found in the way user uses trace ring buffer in a specific way. Only privileged local users (with     CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.
    (CVE-2021-3679)

  - A flaw was found in the Linux kernel's OverlayFS subsystem in the way the user mounts the TmpFS filesystem     with OverlayFS. This flaw allows a local user to gain access to hidden files that should not be     accessible. (CVE-2021-3732)

  - A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may     cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl     (KDSETMDE). The highest threat from this vulnerability is to data confidentiality. (CVE-2021-3753)

  - arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest     OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)

  - In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss can be     triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE: the     vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior     (CVE-2021-38160)

  - arch/x86/kvm/mmu/paging_tmpl.h in the Linux kernel before 5.12.11 incorrectly computes the access     permissions of a shadow page, leading to a missing guest protection page fault. (CVE-2021-38198)

  - drivers/usb/host/max3421-hcd.c in the Linux kernel before 5.13.6 allows physically proximate attackers to     cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain     situations. (CVE-2021-38204)

  - drivers/net/ethernet/xilinx/xilinx_emaclite.c in the Linux kernel before 5.13.3 makes it easier for     attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM     pointer). (CVE-2021-38205)

  - A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in     the Linux kernel through 5.13.13. (CVE-2021-40490)

  - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead     to local escalation of privilege when opening and closing inet sockets with no additional execution     privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)

A local user could     use this flaw to get access to some important data with expected location in memory. (CVE-2023-0597)

  - A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a     type confusion in their initialization function. While it will be often correct, as tuntap devices require     CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This     would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing     network filters. (CVE-2023-1076)

  - In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the     transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list
    -- the list head is all zeroes, this results in a NULL pointer dereference. (CVE-2023-1095)

  - A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the     way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate     their privileges on the system. (CVE-2023-1118)

  - A remote denial of service vulnerability was found in the Linux kernel's TIPC kernel module. The while     loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue.
    Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system     to instantly spike to 100%, causing a denial of service condition. (CVE-2023-1390)

  - A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some     uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an     information leak. (CVE-2023-1513)

  - A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This     flaw allows an attacker to crash the system and possibly cause a kernel information lea (CVE-2023-1611)

  - A flaw use after free in the Linux kernel Xircom 16-bit PCMCIA (PC-card) Ethernet driver was found.A local     user could use this flaw to crash the system or potentially escalate their privileges on the system.
    (CVE-2023-1670)

  - A use-after-free flaw was found in xgene_hwmon_remove in drivers/hwmon/xgene-hwmon.c in the Hardware     Monitoring Linux Kernel Driver (xgene-hwmon). This flaw could allow a local attacker to crash the system     due to a race problem. This vulnerability could even lead to a kernel information leak problem.
    (CVE-2023-1855)

  - A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. In     this flaw, a call to btsdio_remove with an unfinished job, may cause a race problem leading to a UAF on     hdev devices. (CVE-2023-1989)

  - A use-after-free flaw was found in ndlc_remove in drivers/nfc/st-nci/ndlc.c in the Linux Kernel. This flaw     could allow an attacker to crash the system due to a race problem. (CVE-2023-1990)

  - The Linux kernel allows userspace processes to enable mitigations by calling prctl with     PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed     that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to     attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be     observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened     because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that     STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection.
    However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons,     which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target     injection against which STIBP protects. (CVE-2023-1998)

  - An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores     an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or     potentially escalate their privileges on the system. (CVE-2023-2124)

  - A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in     SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal information.
    (CVE-2023-2162)

  - cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

  - atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)

  - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in     the Linux Kernel. The message from user space is not checked properly before transferring into the device.
    This flaw allows a local user to crash the system or potentially cause a denial of service.
    (CVE-2023-28328)

  - hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux kernel through 6.2.9 has a use-after-free     (observed in hci_conn_hash_flush) because of calls to hci_dev_put and hci_conn_put. There is a double free     that may lead to privilege escalation. (CVE-2023-28464)

  - An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer     overflow. (CVE-2023-28772)

  - The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in     drivers/power/supply/da9150-charger.c if a physically proximate attacker unplugs a device.
    (CVE-2023-30772)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

  - When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the     sibling thread after an SMT mode switch potentially resulting in information disclosure. (CVE-2022-27672)

  - A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card     system resource overload, causing a fail in the intel_gvt_dma_map_guest_page function. This issue could     allow a local user to crash the system. (CVE-2022-3707)

  - A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking     configuration (redirecting egress packets to ingress using TC action 'mirred') a local unprivileged user     could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a     retransmission, resulting in a denial of service condition. (CVE-2022-4269)

  - An issue was discovered in the Linux kernel through 6.0.10. l2cap_config_req in net/bluetooth/l2cap_core.c     has an integer wraparound via L2CAP_CONF_REQ packets. (CVE-2022-45934)

  - The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176. We recommend upgrading past commit     a664ec9158eeddd75121d39c9a0758016097fa96 (CVE-2023-0045)

  - There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a     use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can     install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this     socket is disconnected and reused as a listener. If a new socket is created from the listener, the context     is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend     upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

  - A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race     problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 ('net: sched: fix race     condition in qdisc_graft()') not applied yet, then kernel could be affected. (CVE-2023-0590)

  - A memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a     user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2023-1073)

  - A memory leak flaw was found in the Linux kernel's Stream Control Transmission Protocol. This issue may     occur when a user starts a malicious networking service and someone connects to this service. This could     allow a local user to starve resources, causing a denial of service. (CVE-2023-1074)

  - A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a     type confusion in their initialization function. While it will be often correct, as tuntap devices require     CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This     would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing     network filters. (CVE-2023-1076)

  - A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when     plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to     the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED     controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led     structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.
    (CVE-2023-1079)

  - In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the     transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list
    -- the list head is all zeroes, this results in a NULL pointer dereference. (CVE-2023-1095)

  - A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the     way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate     their privileges on the system. (CVE-2023-1118)

  - Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege     Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-     after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this     vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git     commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)

  - A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in     drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur     when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading     to a denial of service. (CVE-2023-1380)

  - A data race flaw was found in the Linux kernel, between where con is allocated and con->sock is set. This     issue leads to a NULL pointer dereference when accessing con->sock->sk in net/tipc/topsrv.c in the tipc     protocol in the Linux kernel. (CVE-2023-1382)

  - A remote denial of service vulnerability was found in the Linux kernel's TIPC kernel module. The while     loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue.
    Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system     to instantly spike to 100%, causing a denial of service condition. (CVE-2023-1390)

  - A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel.
    This issue may allow a local attacker with user privilege to cause a denial of service. (CVE-2023-1582)

  - In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure     (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)

  - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in     the Linux Kernel. The message from user space is not checked properly before transferring into the device.
    This flaw allows a local user to crash the system or potentially cause a denial of service.
    (CVE-2023-28328)

  - do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

  - An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer     overflow. (CVE-2023-28772)
