Description OSIDB Bzimport 2025-12-24 14:09:35 UTC
In the Linux kernel, the following vulnerability has been resolved:

drm/amd: Fix an out of bounds error in BIOS parser

The array is hardcoded to 8 in atomfirmware.h, but firmware provides
a bigger one sometimes. Deferencing the larger array causes an out
of bounds error.

commit 4fc1ba4aa589 ("drm/amd/display: fix array index out of bound error
in bios parser") fixed some of this, but there are two other cases
not covered by it.  Fix those as well.
