Description OSIDB Bzimport 2026-09-17 16:42:08 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu/pm/powerplay: bounds-check voltage index in SMU7 lookup

vddInd and vddcInd fields from VBIOS-parsed tables are used to index into
voltage lookup tables without a bounds check. Return -EINVAL when any
index is out of range.
