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

pds core: fix error handling in pdsc devcmd wait

Fix two cases where pdsc devcmd wait() returns stale success from the completion register instead of an error:

1. FW crash: If firmware stops running, the wait loop breaks early with running=false. The condition "if ((!done || timeout) && running)" is false, so error handling is bypassed and stale status is returned. Check !running first and return -ENXIO.
2. Timeout: If a command times out, err is set to -ETIMEDOUT but then overwritten by pdsc err to errno(status) which reads stale status. Return -ETIMEDOUT immediately after cleaning up.

Both errors now propagate to pdsc devcmd locked() which queues health work for recovery.
