This vulnerability is actively being exploited in the wild. It is a local privilege escalation vulnerability.
Update your Linux kernel to a patched version. Regularly apply security updates to your operating system to address known vulnerabilities.
Technical Analysis
CVE-2022-0492 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2022-0492 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
