The remote SUSE Linux SLES12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:2549-1 advisory.
This update for the Linux Kernel 4.12.14-122_179 fixes several issues.
The following security issues were fixed:
- 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-2024-26930: Fixed double free of the ha->vp_map pointer (bsc#1223681).
- CVE-2024-26828: Fixed underflow in parse_server_interfaces() (bsc#1223363).
- CVE-2024-23307: Fixed Integer Overflow or Wraparound vulnerability in x86 and ARM md, raid, raid5 modules (bsc#1220145).
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.
