CVE-2026-31488 is a Linux kernel vulnerability in the drm/amd/display path affecting the AMDGPU display stack during DSC pre-validation in atomic check handling. The flaw was introduced by a change that reset a CRTC state's mode_changed flag to false when recomputing DSC configuration produced no timing change for a stream. That logic is incorrect when an MST/DSC configuration change occurs in the same KMS commit as another unrelated mode change on the same or related display topology. In that situation, pre_validate_dsc() can incorrectly clear mode_changed even though a DSC-independent mode change is still pending. Because dm_update_crtc_state() may already have created new streams for CRTCs with those unrelated mode changes, the incorrect flag state causes inconsistent stream lifecycle handling: the old stream may not be released as expected, while the new stream may not receive the reference that later code assumes. This results first in a memory leak and can later manifest as a use-after-free in the amdgpu driver when the affected stream is disabled.
