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. The Linux kernel CVE team has assigned CVE-2026-64148 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/net/ethernet/amd/pds_core/dev.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/3231aff8ab26111c54e630b1a200fc43a729dd14 https://git.kernel.org/stable/c/10ae3180095bbe2d378c5b1d6f2f2fd74dda3cc2 https://git.kernel.org/stable/c/784dd2bdc622ed3cc6ef8e113aa1852e252de36f https://git.kernel.org/stable/c/560d559324169fe0583d54c475b5329550a86f71 https://git.kernel.org/stable/c/0e46b6635b03d29807f810c3b415c4755a3f958d
