CVE-2010-1146: The Linux kernel 2.6.33.2 and earlier, when a ReiserFS filesystem exists, does not restrict read or write a...

Security readout for executives and security teams

This is an old Linux kernel local privilege escalation affecting systems that use ReiserFS. If a local user can access the special .reiserfs_priv directory, they may alter filesystem metadata such as extended attributes or ACLs to gain elevated privileges. Exposure is likely limited to legacy Linux systems running kernel 2.6.33.2 or earlier with a ReiserFS filesystem present and local user access available. Treat this as a targeted legacy-platform risk. Prioritize systems with ReiserFS, shared user access, or local code execution exposure; otherwise track through legacy kernel remediation. Mitigation focus: Apply vendor kernel updates containing the ReiserFS .reiserfs_priv permission fix.; Check Linux distribution advisories for the exact fixed kernel package.; Disable or retire unnecessary ReiserFS filesystems where operationally feasible..
