The version of kernel installed on the remote host is prior to 4.14.328-248.540. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2340 advisory.

    2024-06-06: CVE-2023-52477 was added to this advisory.

    A race condition between two functions, lmLogClose() and txEnd(), in the Linux kernel's JFS filesystem can     lead to a use-after-free vulnerability and crash. (CVE-2023-3397)

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

    usb: hub: Guard against accesses to uninitialized BOS descriptors (CVE-2023-52477)

    A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf)     component can be exploited to achieve local privilege escalation.

    If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it     can increment or write to memory locations outside of the allocated buffer.

    We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06. (CVE-2023-5717)

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.
