Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amd/display: Increase block_sequence array size<br /> <br /> [Why]<br /> It&amp;#39;s possible to generate more than 50 steps in hwss_build_fast_sequence,<br /> for example with a 6-pipe asic where all pipes are in one MPC chain. This<br /> overflows the block_sequence buffer and corrupts block_sequence_steps,<br /> causing a crash.<br /> <br /> [How]<br /> Expand block_sequence to 100 items. A naive upper bound on the possible<br /> number of steps for a 6-pipe asic, ignoring the potential for steps to be<br /> mutually exclusive, is 91 with current code, therefore 100 is sufficient.
