CVE-2026-46173

CVE-2026-46173 concerns the Linux kernel. The issue arises when an already-exiting task oopses and make_task_dead() calls do_task_dead() with preemption enabled, while __schedule() must be called with preemption disabled. If a preempted oopsing task is still in the dead-state, finish_task_switch(...

CVE-2026-46173 exit: prevent preemption of oopsing TASK_DEAD task

In the Linux kernel, the following vulnerability has been resolved: exit: prevent preemption of oopsing TASKDEAD task When an already-exiting task oopses, maketaskdead currently calls dotaskdead with preemption enabled. That is forbidden: dotaskdead calls schedule, which has a comment saying...
