2) Improper locking
EUVDB-ID: #VU92035
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2024-26923
CWE-ID:
CWE-667 - Improper Locking
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper locking within the unix_gc() function in net/unix/garbage.c due to garbage collector does not take into account the risk of embryo getting enqueued during the garbage collection. A local user can execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel RT (Live Patch 16 for SLE 15 SP5) to the latest version.
