CVE-2026-64437
CVE-2026-64437 affects the ksmbd component of the Linux kernel. A use-after-free in a deferred file_lock can be triggered by a sequence of SMB2_CLOSE followed by SMB2_CANCEL, allowing an authenticated SMB client to cause a kernel crash (denial of service) via the freed file_lock. The root cause i...

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential UAF in smb2closecachedfid findorcreatecacheddir could grab a new reference after krefput had seen the refcount drop to zero but before cfidlistlock is acquired in smb2closecachedfid, leading to...
CVE-2025-40328
The CVE-2025-40328 issue affects the Linux kernel SMB client. It describes a potential use-after-free in smb2_close_cached_fid() caused by a reference being taken after kref_put() drops to zero but before cfid_list_lock is acquired. The fix switches to kref_put_lock(), ensuring cfid_release() is ...
