The IA32 system call emulation functionality in Linux kernel 2.4.x and 2.6.x before 2.6.22.7, when running on the x86_64 architecture, does not zero extend the eax register after the 32bit entry path to ptrace is used, which might allow local users to gain privileges by triggering an out-of-bounds access to the system call table using the %RAX register.

Security readout for executives and security teams

This is an old Linux kernel flaw that could let a local user gain higher privileges on affected 64-bit systems. It is not a remote-entry vulnerability, but it matters on shared servers, legacy hosts, and systems where untrusted users can run code. Exposure is mainly legacy x86_64 Linux systems running affected 2.4.x or 2.6.x kernels with IA32 compatibility behavior. Modern distributions are unlikely to be exposed, but long-lived appliances, unsupported servers, and frozen embedded builds should be checked. Medium-to-high where legacy Linux still exists. This should not drive emergency action for modern fleets, but any exposed shared or unsupported 64-bit Linux host deserves prompt review because successful exploitation could mean full system compromise. Mitigation focus: Update affected Linux kernels using the relevant vendor security advisory packages.; For source-built kernels, move beyond Linux 2.6.22.7 where applicable.; Retire or isolate unsupported legacy Linux systems that cannot be patched..
