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

  - A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.
    This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015)

  - 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 flaw was found in the Linux kernel's TUN/TAP device driver functionality in how a user     registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw     allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4744)

  - A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The     resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be     used to leak the contents. We recommend upgrading past version 6.1.8 or commit     739790605705ddcf18f21782b9c99ad7d53a8c11 (CVE-2023-0458)

  - Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec     allowing a user to bypass the 'access_ok' check and pass a kernel pointer to copy_from_user(). This would     allow an attacker to leak information. We recommend upgrading beyond commit     74e19ef0ff8061ef55957c3abd71614ef0f42f47 (CVE-2023-0459)

  - A use-after-free flaw was found in the Linux kernel's core dump subsystem. This flaw allows a local user     to crash the system. Only if patch 390031c94211 ('coredump: Use the vma snapshot in fill_files_note') not     applied yet, then kernel could be affected. (CVE-2023-1249)

  - 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 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 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)

  - A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local     privilege escalation. The io_file_get_fixed function lacks the presence of ctx->uring_lock which can lead     to a Use-After-Free vulnerability due a race condition with fixed files getting unregistered. We recommend     upgrading past commit da24142b1ef9fd5d36b76e36bab328a5b27523e8. (CVE-2023-1872)

  - 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)

  - A flaw was found in the Linux kernel's udmabuf device driver. The specific flaw exists within a fault     handler. The issue results from the lack of proper validation of user-supplied data, which can result in a     memory access past the end of an array. An attacker can leverage this vulnerability to escalate privileges     and execute arbitrary code in the context of the kernel. (CVE-2023-2008)

  - 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)

  - A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA in the Linux     Kernel. The improper cleanup results in out-of-boundary read, where a local user can utilize this problem     to crash the system or escalation of privilege. (CVE-2023-2176)

  - A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in     Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A     local user could use this flaw to crash the system or potentially cause a denial of service.
    (CVE-2023-2177)

  - An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The     userspace 'data->block[0]' variable was not capped to a number between 0-255 and was used as the size of a     memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to     crash the system or potentially achieve code execution. (CVE-2023-2194)

  - Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority because it was     the duplicate of CVE-2023-31436. (CVE-2023-2248)

  - A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

  - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2023-33203. Reason: This candidate is a     reservation duplicate of CVE-2023-33203. Notes: All CVE users should reference CVE-2023-33203 instead of     this candidate. All references and descriptions in this candidate have been removed to prevent accidental     usage. (CVE-2023-2483)

  - A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors. (CVE-2023-2513)

  - 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 arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64     lacks consistency checks for CR0 and CR4. (CVE-2023-30456)

  - qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX. (CVE-2023-31436)

  - In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests     can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users     can obtain root privileges. This occurs because anonymous sets are mishandled. (CVE-2023-32233)

  - The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in     drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based device.
    (CVE-2023-33203)

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

  - An issue was discovered in netfilter in the Linux kernel before 5.10. There can be a use-after-free in the     packet processing context, because the per-CPU sequence count is mishandled during concurrent iptables     rules replacement. This could be exploited with the CAP_NET_ADMIN capability in an unprivileged namespace.
    NOTE: cc00bca was reverted in 5.12. (CVE-2020-36694)

  - A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The     resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be     used to leak the contents.

This would     allow an attacker to leak information. We recommend upgrading beyond commit     74e19ef0ff8061ef55957c3abd71614ef0f42f47 (CVE-2023-0459)

  - A flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness,     potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field     that overlaps with rec->tx_ready. (CVE-2023-1075)

  - A vulnerability was found in the HCI sockets implementation due to a missing capability check in     net/bluetooth/hci_sock.c in the Linux Kernel. This flaw allows an attacker to unauthorized execution of     management commands, compromising the confidentiality, integrity, and availability of Bluetooth     communication. (CVE-2023-2002)

  - 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)

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 :

  - An issue was discovered in netfilter in the Linux kernel before 5.10. There can be a use-after-free in the     packet processing context, because the per-CPU sequence count is mishandled during concurrent iptables     rules replacement. This could be exploited with the CAP_NET_ADMIN capability in an unprivileged namespace.
    NOTE: cc00bca was reverted in 5.12. (CVE-2020-36694)

  - A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The     resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be     used to leak the contents. We recommend upgrading past version 6.1.8 or commit     739790605705ddcf18f21782b9c99ad7d53a8c11 (CVE-2023-0458)

  - Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec     allowing a user to bypass the 'access_ok' check and pass a kernel pointer to copy_from_user(). This would     allow an attacker to leak information. We recommend upgrading beyond commit     74e19ef0ff8061ef55957c3abd71614ef0f42f47 (CVE-2023-0459)

  - A flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness,     potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field     that overlaps with rec->tx_ready. (CVE-2023-1075)

  - A vulnerability was found in the HCI sockets implementation due to a missing capability check in     net/bluetooth/hci_sock.c in the Linux Kernel. This flaw allows an attacker to unauthorized execution of     management commands, compromising the confidentiality, integrity, and availability of Bluetooth     communication. (CVE-2023-2002)

  - 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)

  - A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in     Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A     local user could use this flaw to crash the system or potentially cause a denial of service.
    (CVE-2023-2177)

  - Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority because it was     the duplicate of CVE-2023-31436. (CVE-2023-2248)

  - A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

  - An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a     blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is     called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event,     down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and     down(&fepriv->sem) may block the process. (CVE-2023-31084)

  - A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the     Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading     to a kernel information leak. (CVE-2023-3141)

  - qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX. (CVE-2023-31436)

  - A use after free issue was discovered in driver/firewire in outbound_phy_packet_callback in the Linux     Kernel. In this flaw a local attacker with special privilege may cause a use after free problem when     queue_event() fails. (CVE-2023-3159)

  - A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and     font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds     occurs leading to undefined behavior and possible denial of service. (CVE-2023-3161)

  - In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests     can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users     can obtain root privileges. This occurs because anonymous sets are mishandled. (CVE-2023-32233)

  - An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

  - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2023-35823. Reason: This candidate is a     reservation duplicate of CVE-2023-35823. Notes: All CVE users should reference CVE-2023-35823 instead of     this candidate. All references and descriptions in this candidate have been removed to prevent accidental     usage. (CVE-2023-3327)

  - An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against     attackers with the stated 'When modifying the block device while it is mounted by the filesystem' access.
    (CVE-2023-34256)

  - An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation. (CVE-2023-35788)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in saa7134_finidev in     drivers/media/pci/saa7134/saa7134-core.c. (CVE-2023-35823)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in dm1105_remove in     drivers/media/pci/dm1105/dm1105.c. (CVE-2023-35824)

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    CVE-2022-4269

        William Zhao discovered that a flaw in the Traffic Control (TC)         subsystem when using a specific networking configuration         (redirecting egress packets to ingress using TC action mirred),         may allow a local unprivileged user to cause a denial of service         (triggering a CPU soft lockup).

    CVE-2022-39189

        Jann Horn discovered that TLB flush operations are mishandled in         the KVM subsystem in certain KVM_VCPU_PREEMPTED situations, which         may allow an unprivileged guest user to compromise the guest         kernel.

    CVE-2023-1206

        It was discovered that the networking stack permits attackers to         force hash collisions in the IPv6 connection lookup table, which         may result in denial of service (significant increase in the cost         of lookups, increased CPU utilization).

    CVE-2023-1380

        Jisoo Jang reported a heap out-of-bounds read in the brcmfmac         Wi-Fi driver. On systems using this driver, a local user could         exploit this to read sensitive information or to cause a denial of         service.

    CVE-2023-2002

        Ruiahn Li reported an incorrect permissions check in the Bluetooth         subsystem. A local user could exploit this to reconfigure local         Bluetooth interfaces, resulting in information leaks, spoofing, or         denial of service (loss of connection).

    CVE-2023-2007

        Lucas Leong and Reno Robert discovered a         time-of-check-to-time-of-use flaw in the dpt_i2o SCSI controller         driver. A local user with access to a SCSI device using this         driver could exploit this for privilege escalation.

        This flaw has been mitigated by removing support for the I2OUSRCMD         operation.

    CVE-2023-2124

        Kyle Zeng, Akshay Ajayan and Fish Wang discovered that missing         metadata validation may result in denial of service or potential         privilege escalation if a corrupted XFS disk image is mounted.

    CVE-2023-2269

        Zheng Zhang reported that improper handling of locking in the         device mapper implementation may result in denial of service.

    CVE-2023-2898

        It was discovered that missing sanitising in the f2fs file system         may result in denial of service if a malformed file system is         accessed.

    CVE-2023-3090

        It was discovered that missing initialization in ipvlan networking         may lead to an out-of-bounds write vulnerability, resulting in         denial of service or potentially the execution of arbitrary code.

    CVE-2023-3111

        The TOTE Robot tool found a flaw in the Btrfs filesystem driver         that can lead to a use-after-free. It's unclear whether an         unprivileged user can exploit this.

    CVE-2023-3141

        A flaw was discovered in the r592 memstick driver that could lead         to a use-after-free after the driver is removed or unbound from a         device. The security impact of this is unclear.

    CVE-2023-3212

        Yang Lan discovered that missing validation in the GFS2 filesystem         could result in denial of service via a NULL pointer dereference         when mounting a malformed GFS2 filesystem.

    CVE-2023-3268

        It was discovered that an out-of-bounds memory access in relayfs         could result in denial of service or an information leak.

    CVE-2023-3338

        Davide Ornaghi discovered a flaw in the DECnet protocol         implementation which could lead to a null pointer dereference or         use-after-free. A local user can exploit this to cause a denial of         service (crash or memory corruption) and probably for privilege         escalation.

        This flaw has been mitigated by removing the DECnet protocol         implementation.

    CVE-2023-3389

        Querijn Voet discovered a use-after-free in the io_uring         subsystem, which may result in denial of service or privilege         escalation.

    CVE-2023-3609, CVE-2023-3776. CVE-2023-4128

        It was discovered that a use-after-free in the cls_fw, cls_u32,         cls_route and network classifiers may result in denial of service         or potential local privilege escalation.

    CVE-2023-3611

        It was discovered that an out-of-bounds write in the traffic         control subsystem for the Quick Fair Queueing scheduler (QFQ) may         result in denial of service or privilege escalation.

    CVE-2023-3772

        Lin Ma discovered a NULL pointer dereference flaw in the XFRM         subsystem which may result in denial of service.
