CVE-2026-72472
A flaw was found in the Network File System NFS component of the Linux kernel. Inadequate synchronization during the traversal of the file lock list can lead to a use-after-free UAF vulnerability. This occurs when certain functions release file locks prematurely while iterating, potentially...
