The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2232-1 advisory.

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized     disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5753)

  - An issue was discovered in the Linux kernel before 5.8. lib/nlattr.c allows attackers to cause a denial of     service (unbounded recursion) via a nested Netlink policy with a back reference. (CVE-2020-36691)

  - 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)

  - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and     SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a     user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)

  - In pppol2tp_create of l2tp_ppp.c, there is a possible use after free due to a race condition. This could     lead to local escalation of privilege with System execution privileges needed. User interaction is not     needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-186777253References:
    Upstream kernel (CVE-2022-20567)

  - The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer     overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send     buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer     to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC     message with garbage data is still correctly formed according to the specification and is passed forward     to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the     allocated buffer space. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H (CVE-2022-43945)

  - A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

  - 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 flaw possibility of memory leak in the Linux kernel cpu_entry_area mapping of X86 CPU data to memory was     found in the way user can guess location of exception stack(s) or other important data. 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)
