Description OSIDB Bzimport 2026-09-17 17:50:12 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amd/powerplay: fix VoltageObjectInfo zero-stride loop and OOB read

Reject voltage objects whose usSize is smaller than the header or would
advance the cursor past the table end, preventing an infinite loop or
heap OOB read when the VBIOS supplies a malformed VoltageObjectInfo table.
