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-2024-40902 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"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-2024-40902 advisory.
- In the Linux kernel, the following vulnerability has been resolved: jfs: xattr: fix buffer overflow for
invalid xattr When an xattr size is not what is expected, it is printed out to the kernel log in hex
format as a form of debugging. But when that xattr size is bigger than the expected size, printing it out
can cause an access off the end of the buffer. Fix this all up by properly restricting the size of the
debug hex dump in the kernel log. (CVE-2024-40902)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
