The remote SUSE Linux SLES12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:3015-1 advisory.
This update for the Linux Kernel 4.12.14-122_216 fixes several issues.
The following security issues were fixed:
- CVE-2021-47378: Fixed use-after-free by destroying cm id before destroying qp (bsc#1225202).
- CVE-2024-27398: Fixed use-after-free bugs caused by sco_sock_timeout (bsc#1225013).
- CVE-2024-35950: drm/client: Fully protect modes with dev->mode_config.mutex (bsc#1225310).
- CVE-2021-47383: Fixed out-of-bound vmalloc access in imageblit (bsc#1225211).
- CVE-2024-26923: Fixed false-positive lockdep splat for spin_lock() in __unix_gc() (bsc#1223683).
- CVE-2024-26828: Fixed underflow in parse_server_interfaces() (bsc#1223363).
- CVE-2021-46955: Fixed an out-of-bounds read with openvswitch, when fragmenting IPv4 packets (bsc#1220537).
- CVE-2023-1829: Fixed a use-after-free vulnerability in the control index filter (tcindex) (bsc#1210619).
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.
