Vulnerability from github – Published: 2026-07-19 18:31 – Updated: 2026-07-20 15:32

Details

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:

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.
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.

Severity

7.5 (High)
