The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:2145-1 advisory.
This update for the Linux Kernel 5.3.18-150300_59_144 fixes several issues.
The following security issues were fixed:
- CVE-2021-46955: Fixed an out-of-bounds read with openvswitch, when fragmenting IPv4 packets (bsc#1220537).
- CVE-2023-6931: Fixed an out of bounds write in the Performance Events subsystem when adding a new event (bsc#1218259).
- CVE-2024-26852: Fixed use-after-free in ip6_route_mpath_notify() (bsc#1223059).
Tenable has extracted the preceding description block directly from the SUSE security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
