CISA KEV Advisory
Linux Kernel Privilege Escalation Vulnerability
The futex_requeue function in kernel/futex.c in Linux kernel does not ensure that calls have two different futex addresses, which allows local users to gain privileges.
Apply updates per vendor instructions.
Risk Analysis
This Linux kernel vulnerability allows a local user to gain elevated privileges due to improper handling of futex addresses. The high EPSS score of 0.72190 indicates a significant likelihood of exploitation, and its inclusion in the KEV catalog confirms it has been actively exploited.
This vulnerability has been actively exploited in the wild, as confirmed by its presence in the KEV catalog. Local attackers are leveraging this flaw to escalate privileges.
Ensure your Linux kernel is updated to a patched version to address this privilege escalation vulnerability. Regularly apply security updates to your operating system.
Technical Analysis
CVE-2014-3153 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-2014-3153 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.
