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

  - In the Linux kernel, the following vulnerability has been resolved: cifs: Fix server re-repick on     subrequest retry When a subrequest is marked for needing retry, netfs will call cifs_prepare_write() which     will make cifs repick the server for the op before renegotiating credits; it then calls cifs_issue_write()     which invokes smb2_async_writev() - which re-repicks the server. If a different server is then selected,     this causes the increment of server->in_flight to happen against one record and the decrement to happen     against another, leading to misaccounting. Fix this by just removing the repick code in     smb2_async_writev(). As this is only called from netfslib-driven code, cifs_prepare_write() should always     have been called first, and so server should never be NULL and the preparatory step is repeated in the     event that we do a retry. The problem manifests as a warning looking something like: WARNING: CPU: 4 PID:
    72896 at fs/smb/client/smb2ops.c:97 smb2_add_credits+0x3f0/0x9e0 [cifs] ... RIP:
    0010:smb2_add_credits+0x3f0/0x9e0 [cifs] ... smb2_writev_callback+0x334/0x560 [cifs]     cifs_demultiplex_thread+0x77a/0x11b0 [cifs] kthread+0x187/0x1d0 ret_from_fork+0x34/0x60     ret_from_fork_asm+0x1a/0x30 Which may be triggered by a number of different xfstests running against an     Azure server in multichannel mode. generic/249 seems the most repeatable, but generic/215, generic/249 and     generic/308 may also show it. (CVE-2024-42256)

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