CVE-2026-98990

A vulnerability exists in the Linux kernel where the functions shrink_submounts() and mark_mounts_for_expiry() fail to properly validate submount references before unmounting. Because unmounting the first mount alters the tree structure for subsequent operations, propagate_umount() may incorrectl...
