Linux platform/x86/amd/pmc - IRQ1 wakeup disabled unconditionally: The AMD PMC driver disabled IRQ1 wakeup in cases
CVE-2025-21645Control plane, storage & DevOpscurated
Impact
The AMD PMC driver disabled IRQ1 wakeup in cases where i8042 had never enabled it, corrupting interrupt wakeup configuration. Low-severity platform-driver correctness bug; included because the amd/pmc driver autoloads on AMD hosts whether or not the platform needs it, and unnecessary loaded drivers are unnecessary attack surface.
Who can reach it
Local, through platform power-management paths.
What to do
Distro kernel update plus reboot, or blacklist the module on server images where power management is handled by the BMC and BIOS anyway.
