What to do
AI-suggested
A fix is available that increases the block_sequence array size to 100 items to prevent overflow. Users should apply the updated Linux kernel version containing this fix once it is released. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's AMD display driver (drm/amd/display) involves a buffer overflow in the block_sequence array due to insufficient size. This can cause a crash when more than 50 steps are generated in hwss_build_fast_sequence, particularly on 6-pipe ASICs with all pipes in one MPC chain. The issue is addressed by increasing the block_sequence array size to 100 to prevent overflow.
