kernel: procfs: avoid fetching build ID while holding VMA lock
A deadlock vulnerability was found in the procfs PROCMAPQUERY ioctl handler. When fetching the optional build ID while holding the VMA lock mmaplock, a circular lock dependency can occur with the inode mutex, causing a system deadlock...

CVE-2026-93241
The Linux kernel contains a vulnerability in memcg where dying tasks can bypass reclaim and the oom killer once the oom_reaper has finished its task. This occurs because the oom_reaper is a best-effort, one-shot process; if it fails to acquire the mmap_lock in read mode (e.g., due to a sibling th...
