CVE-2026-99130

A flaw was found in the Linux kernel's io_uring subsystem. A local attacker can exploit this vulnerability to cause a Denial of Service (DoS) by triggering an infinite loop during process exit. This issue occurs when an exiting task attempts to cancel requests on an io_uring ring with pending work that only another thread is permitted to execute, preventing the task from completing its exit sequence. Consequently, the thread continuously consumes processor resources, which may lead to system unresponsiveness or a kernel crash.
