CVE-2025-38614
The CVE CVE-2025-38614 affects the Linux kernel eventpoll/epoll component. The vulnerability stemmed from semi-unbounded recursion in ep_loop_check_proc() and related upwards/downwards path checks, enabling depths up to ~500 in certain graphs before a fix. The fix introduces subtree depth trackin...
