Linux kernel 2.4.10 through 2.4.21-pre4 does not properly handle the O_DIRECT feature, which allows local attackers with write privileges to read portions of previously deleted files, or cause file system corruption.

Security readout for executives and security teams

This is an old Linux kernel flaw affecting 2.4.10 through 2.4.21-pre4. A local user with write privileges could potentially read remnants of deleted files or corrupt the filesystem through improper O_DIRECT handling. Exposure is most likely limited to legacy Linux systems still running kernel 2.4.10 through 2.4.21-pre4, especially shared systems where untrusted or semi-trusted users have local write access. Treat this as a legacy-risk check, not a broad emergency. Prioritize any production, shared-hosting, or regulated-data system still running affected 2.4 kernels for upgrade or isolation. Mitigation focus: Inventory systems for Linux kernel 2.4.10 through 2.4.21-pre4.; Apply the relevant vendor kernel update from Debian, Red Hat, or Mandrake guidance.; Upgrade legacy hosts to a supported Linux kernel where feasible..
