Multiple race conditions in the terminal layer in Linux 2.4.x, and 2.6.x before 2.6.9, allow (1) local users to obtain portions of kernel data via a TIOCSETD ioctl call to a terminal interface that is being accessed by another thread, or (2) remote attackers to cause a denial of service (panic) by switching from console to PPP line discipline, then quickly sending data that is received during the switch.

Security readout for executives and security teams

This is an old Linux kernel terminal-layer race condition. On affected kernels, a local user may read fragments of kernel data, and a remote attacker may trigger a kernel panic in a specific PPP line-discipline switching scenario. The main business risk is legacy Linux systems or appliances still running vulnerable kernels. Exposure is limited to systems running Linux 2.4.x or Linux 2.6.x before 2.6.9. The source bundle does not provide CPEs or a complete product matrix. Legacy servers, embedded systems, and appliances should be checked for kernel version and vendor backported fixes. Prioritize this when legacy Linux, embedded devices, or unsupported appliances remain in production. Modern supported Linux systems are unlikely to be exposed, but untracked legacy kernels can create outage and data exposure risk. Mitigation focus: Upgrade affected Linux kernels to a vendor-fixed release or later supported kernel.; Check Red Hat, Mandriva, Fedora, or relevant vendor advisories for backported fixes.; Retire or isolate systems that must remain on obsolete 2.4.x or pre-2.6.9 kernels..
