Description
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.

Can you explain this vulnerability to me?

This vulnerability is an out of bounds error in the Linux kernel's AMD DRM BIOS parser. The code uses a hardcoded array size of 8, but sometimes the firmware provides a larger array. Dereferencing this larger array causes an out of bounds error, which was partially fixed in a previous commit but still had two uncovered cases that were later fixed.


How can this vulnerability impact me? :

The vulnerability can cause out of bounds memory access in the Linux kernel's AMD DRM BIOS parser, which may lead to system instability, crashes, or potential security risks such as memory corruption.
