CVE-2026-64148
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.
