Summary
The ptrace functionality (ptrace.c) in Linux kernel 2.6 before 2.6.14.2, using CLONE_THREAD, does not use the thread group ID to check whether it is attaching to itself, which allows local users to cause a denial of service (crash).
Exploit prediction
0.43% chance of exploitation in the next 30 days, higher than 37% of all scored CVEs (FIRST EPSS, 2026-11-08).
