"The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by a vulnerability as
referenced in the SUSE-SU-2024:1813-1 advisory.

    The SUSE Linux Enterprise 15 SP5 RT kernel was updated to receive various security bugfixes.

    This update fixes a regression with kerberized nfs4 shares in the previous update (bsc#1223858).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
