- Summary
- CVE-2025-38080 affecting package kernel for versions less than 6.6.96.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Increase block_sequence array size
[Why] It's possible to generate more than 50 steps in hwssbuildfastsequence, for example with a 6-pipe asic where all pipes are in one MPC chain. This overflows the blocksequence buffer and corrupts blocksequencesteps, causing a crash.
[How] Expand block_sequence to 100 items. A naive upper bound on the possible number of steps for a 6-pipe asic, ignoring the potential for steps to be mutually exclusive, is 91 with current code, therefore 100 is sufficient.
