CVE-2026-90162

A flaw was found in ksmbd, a kernel module for SMB3 protocol support in the Linux kernel. A race condition exists in the smb2lock function, where a lock object can be freed while still being referenced, known as a Use-After-Free, and then freed again, known as a Double-Free. This occurs when...

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fixed the UAF of struct filelock in SMB2LOCK with deferred lock cancellation. When a blocking byte-range lock request is deferred in the FILELOCKDEFERRED path, ksmbd registers the asynchronous work into the connection’s...

SUSE CVE-2026-90156

In the Linux kernel, the following vulnerability has been resolved: ksmbd: safely discard unregistered deferred locks When vfslockfile defers a lock, smb2lock puts its ksmbdlock on rollbacklist before allocating and registering the asynchronous work. If either operation fails, rollback assumes th...
