CISA KEV Advisory

Linux Kernel Privilege Escalation Vulnerability

Linux kernel contains an improper initialization vulnerability where an unprivileged local user could escalate their privileges on the system. This vulnerability has the moniker of "Dirty Pipe."

Added to KEV: 2022-04-25Federal patch deadline: 2022-05-16

Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

The Linux kernel contains an improper initialization vulnerability, dubbed "Dirty Pipe," which allows an unprivileged local user to escalate their privileges to root. With an EPSS score of 0.83439 and inclusion in CISA's KEV, this vulnerability is highly likely to be exploited for privilege escalation.

This vulnerability is actively being exploited in the wild, confirming its use by attackers. Exploitation requires local access to the system but can lead to full system compromise.

Recommended Action

Linux system administrators should apply the latest kernel updates to patch the "Dirty Pipe" vulnerability. Regularly review and restrict user privileges to minimize the impact of local exploits.

Technical Analysis

CVE-2022-0847 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-2022-0847 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.
