The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-26585 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- In the Linux kernel, the following vulnerability has been resolved: tls: fix race between tx work
scheduling and socket close Similarly to previous commit, the submitting thread (recvmsg/sendmsg) May exit
as soon as the async crypto handler calls complete(). Reorder scheduling the work before calling
complete(). This seems more logical in the first place, as it's the inverse order of what the submitting
thread will do. (CVE-2024-26585)
