In the Linux kernel, the following vulnerability has been resolved: smb: client: resolve SWN tcon from live registrations cifs_swn_notify() looks up… (CVE-2026-64401)CVE-2026-64401 0 A use-after-free vulnerability in the Linux kernel's SMB client implementation (cifs_swn_notify) has been resolved. The issue arises because the function uses a cached tcon pointer that may reference freed memory when multiple mounts share the same registration ID. This can lead to unsafe operations on freed objects and lock order violations. The fix involves storing only stable witness identity information and dynamically resolving a live tcon at notification time, ensuring safe reference handling and preserving intended behavior.
