In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Adjust VSDB parser for replay feature
At some point, the IEEE ID identification for the replay check in the AMD EDID was added. However, this check causes the following out-of-bounds issues when using KASAN:
[ 27.804016] BUG: KASAN: slab-out-of-bounds in amdgpudmupdatefreesynccaps+0xefa/0x17a0 [amdgpu] [ 27.804788] Read of size 1 at addr ffff8881647fdb00 by task systemd-udevd/383

This is caused because the ID extraction happens outside of the range of the edid lenght. This commit addresses this issue by considering the amdvsdbblock size.
