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

  - mptcp: stricter state check in mptcp_worker As reported by Christoph, the mptcp protocol can run the     worker when the relevant msk socket is in an unexpected state: connect() // incoming reset + fastclose //     the mptcp worker is scheduled mptcp_disconnect() // msk is now CLOSED listen() mptcp_worker() Leading to     the following splat: divide error: 0000 [#1] PREEMPT SMP CPU: 1 PID: 21 Comm: kworker/1:0 Not tainted     6.3.0-rc1-gde5e8fd0123c #11 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.11.0-2.el7     04/01/2014 Workqueue: events mptcp_worker RIP: 0010:__tcp_select_window+0x22c/0x4b0     net/ipv4/tcp_output.c:3018 RSP: 0018:ffffc900000b3c98 EFLAGS: 00010293 RAX: 000000000000ffd7 RBX:

    (CVE-2023-54176)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-169 advisory.

    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)

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

    skbuff: Fix a race between coalescing and releasing SKBs (CVE-2023-53186)
