CVE-2026-68233

A flaw was found in the drm/vc4 component of the Linux kernel. A logic error in the BO cache timer shutdown process allows the timer to be rearmed even after it has been destroyed. This can lead to work being queued again after teardown, potentially causing system instability or a denial of servi...

CVE-2026-68303

A flaw was found in the Linux kernel's drm/vc4 drivers, specifically in the hvs and v3d components. When these drivers are being removed, they attempt to access memory that has already been freed. This occurs because they try to retrieve driver data from a master device that is no longer availabl...
