2) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU61245
Risk: Low
CVSSv4.0: 8.5 [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:A/U:Clear]
CVE-ID: CVE-2022-0492
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a logic error within the cgroup_release_agent_write() function in kernel/cgroup/cgroup-v1.c. A local user can use the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation.
MitigationUpdate the affected package the Linux Kernel (Live Patch 12 for SLE 15 SP2) to the latest version.
