CVE-2026-68236

A flaw was found in the Linux kernel's drm/amd/display component. Specifically, within the dmupdatecrtcstate function, a stream pointer is released but not subsequently set to NULL. This can lead to a double release of the same pointer if an error occurs later in the process, creating a...

kernel: drm/amd/display: Do not skip unrelated mode changes in DSC validation

A flaw was found in the Linux kernel's AMD display component. This vulnerability arises from incorrect validation of display mode changes during Display Stream Compression DSC processing. A local attacker could exploit this by initiating specific display configuration changes, which may lead to a...
