    In the Linux kernel, the following vulnerability has been resolved:

    dm integrity: Fix UAF in dm_integrity_dtr() (CVE-2022-50889)

    The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the     kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a     syscall. The kernel also does not issue an IBPB immediately during the syscall. (CVE-2023-0045)

    A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could     allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to     the root user via arbitrary code execution. (CVE-2023-0179)

    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)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0459)

    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)

    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)

    In the Linux kernel 6.0.8, there is a use-after-free in run_unpack in fs/ntfs3/run.c, related to a     difference between NTFS sector size and media sector size. (CVE-2023-26544)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - fs/ntfs3: Fix slab-out-of-bounds in r_page When PAGE_SIZE is 64K, if read_log_page is called by     log_read_rst for the first time, the size of *buffer would be equal to DefaultLogPageSize(4K).But for
    *buffer operations like memcpy, if the memory area size(n) which being assigned to buffer is larger than     4K (log->page_size(64K) or bytes(64K-page_off)), it will cause an out of boundary error. Call trace: [...]     kasan_report+0x44/0x130 check_memory_region+0xf8/0x1a0 memcpy+0xc8/0x100 ntfs_read_run_nb+0x20c/0x460     read_log_page+0xd0/0x1f4 log_read_rst+0x110/0x75c log_replay+0x1e8/0x4aa0     ntfs_loadlog_and_replay+0x290/0x2d0 ntfs_fill_super+0x508/0xec0 get_tree_bdev+0x1fc/0x34c [...] Fix this     by setting variable r_page to NULL in log_read_rst. (CVE-2022-50869)

Note that Nessus relies on the presence of the package as reported by the vendor.
