A vulnerability in the Linux kernel related to namespace handling has been resolved. The issue involves pseudo dentries, which are special directory entries for pipes, sockets, and other files that are not part of the normal filesystem hierarchy. These pseudo dentries should not become the root of a mount, but bind mounting /proc/self/fd/<fd> can cause this to happen. This leads to a race condition where a dentry can be freed while still being accessed, potentially causing instability. The fix prevents cloning a mount whose root is a pseudo dentry with the DCACHE_NORCU flag. Join the discussion | GCVE Database | 10/23/2026, 15:31:33 UTC Added: 10/23/2026, 18:43:27 UTC |
