CVE-2023-54150
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.
