The tomoyo_mount_acl function in security/tomoyo/mount.c in the Linux kernel before 2.6.39.2 calls the kern_path function with arguments taken directly from a mount system call, which allows local users to cause a denial of service (OOPS) or possibly have unspecified other impact via a NULL value for the device name.

Security readout for executives and security teams

This is an old Linux kernel flaw in TOMOYO mount handling. A local user could trigger a kernel crash by passing a NULL device name through a mount request. The main documented impact is denial of service; other impact was not specified in the sources. Exposure is most likely on legacy systems running Linux kernels older than 2.6.39.2 with the TOMOYO code path present. The bundle does not identify affected distributions, configurations, or supported vendor package versions. Treat this as a legacy platform risk. It is not currently flagged as exploited, but affected systems can be crashed by local users and should be upgraded or retired. Mitigation focus: Upgrade to a vendor-supported kernel containing the 2.6.39.2 TOMOYO fix.; Check Linux distribution or hardware vendor advisories for backported fixes.; Prioritize replacement of unsupported legacy kernels..
