Description
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.
