CVE-2026-53121Control plane, storage & DevOpscurated
Impact
On failure to set the energy-performance preference, amd_pstate_epp_cpu_init() returns without freeing what it allocated. Another slow leak in the AMD CPU frequency driver, hit on the error path - which is the path a misconfigured or partially-supported platform takes repeatedly rather than once.
Who can reach it
Local, on the amd-pstate initialisation error path.
What to do
Distro kernel update plus reboot. Batch with the other amd-pstate fixes.
