CVE-2022-0492: A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function.

Noroxi assessment

Priority: This week (action score 63/100)

CISA has confirmed exploitation in the wild (Jun 2, 2026). Remediation deadline for US federal agencies: Jun 5, 2026.
A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
Probability of exploitation in the next 30 days: 5.5% (FIRST EPSS); higher than 92.8% of all records.
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: kernel-tools-libs-devel (AlmaLinux:8) 4.18.0-348.20.1.el8_5; linux (Debian:11) 5.10.103-1; linux (Debian:12) 5.16.7-1.
Mentioned 6 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to kernel-tools-libs-devel (AlmaLinux:8) 4.18.0-348.20.1.el8_5; linux (Debian:11) 5.10.103-1; linux (Debian:12) 5.16.7-1 or later.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
