The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:2109-1 advisory.
This update for the Linux Kernel 5.3.18-150200_24_157 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-2023-52628: Fixed 4-byte stack OOB write in nftables (bsc#1222118).
- 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.
