CVE-2026-53085

The CVE-2026-53085 issue affects the Linux kernel BPF subsystem where the open-coded task_vma iterator reads task->mm locklessly and uses mmap_read_trylock() without taking an mm reference, risking use-after-free if the task exits concurrently. The patch reads task->mm with a trylock on all...
