CVE-2021-4154 (opens in a new tab)Amendment
The SLES security team deemed this advisory irrelevant for SLES:15.3.
NVD Description
Note: Versions mentioned in the description apply only to the upstream dlm-kmp-rt package and not the dlm-kmp-rt package as distributed by SLES.
A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.
