CISA KEV Advisory
Linux Kernel PIE Stack Buffer Corruption Vulnerability
Linux kernel contains a position-independent executable (PIE) stack buffer corruption vulnerability in load_elf_ binary() that allows a local attacker to escalate privileges.
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Risk Analysis
This Linux kernel vulnerability involves a stack buffer corruption that could allow a local attacker to gain elevated privileges. With an EPSS score of 0.54194, there is a high likelihood of exploitation. Its presence in CISA's KEV catalog confirms it is a critical threat.
This vulnerability has been actively exploited in the wild and is included in CISA's Known Exploited Vulnerabilities catalog. Exploitation requires local access to the affected system.
System administrators should apply the latest security patches for the Linux kernel. Ensure that systems are configured with the principle of least privilege to limit the impact of local privilege escalation.
Technical Analysis
CVE-2017-1000253 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-2017-1000253 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.
