Affected: Alpaquita:23: linux-lts, Alpaquita:25: linux-lts, Alpaquita:stream: linux-lts

In the Linux kernel, the following vulnerability has been resolved:

smb: server: let send_done handle a completion without IB_SEND_SIGNALED

With smbdirect_send_batch processing we likely have requests without IB_SEND_SIGNALED, which will be destroyed in the final request that has IB_SEND_SIGNALED set.

If the connection is broken all requests are signaled even without explicit IB_SEND_SIGNALED.

Ein Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um nicht näher spezifizierte Angriffe durchzuführen, welche zu einem Denial-of-Service-Zustand, einer Rechteausweitung, der Ausführung von Code oder einer Speicherbeschädigung führen könnten.
