The version of kernel installed on the remote host is prior to 4.14.334-177.552. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2024-1899 advisory.

    2024-07-03: CVE-2023-52813 was added to this advisory.

    2024-06-07: CVE-2023-52881 was added to this advisory.

    2024-02-01: CVE-2023-0590 was added to this advisory.

    2024-01-19: CVE-2023-52340 was added to this advisory.

    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. (CVE-2023-0590)

    When a router encounters an IPv6 packet too big to transmit to the next-hop, it returns an ICMP6 Packet     Too Big (PTB) message to the sender. The sender caches this updated Maximum Transmission Unit (MTU) so it     knows not to exceed this value when subsequently routing to the same host.

    In Linux kernels prior to 6.3, garbage collection is run on the IPv6 Destination Route Cache if the number     of entries exceeds a threshold when adding the destination to the cache. This garbage collection examines     every entry in the cache while holding a lock. In these affected kernel versions, a flood of the IPv6     ICMP6 PTB messages could cause high lock contention and increased CPU usage, leading to a Denial-of-     Service.

    The fix backports the garbage collection improvements from Linux kernel 6.3 by bringing the IPv6 code     closer to the IPv4 code, which does not have this issue.

    Patch: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=af6d10345ca76670c1b7c3     7799f0d5576ccef277 (CVE-2023-52340)

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

    crypto: pcrypt - Fix hungtask for PADATA_RESET (CVE-2023-52813)

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

    tcp: do not accept ACK of bytes we never sent (CVE-2023-52881)

    A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve     local privilege escalation.

    A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object     which is freed by another thread.

    We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1. (CVE-2023-6932)

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.
