In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Serialize the scheduler timeout handlers V3D exposes several… (CVE-2026-74638)CVE-2026-74638 0 A concurrency issue in the Linux kernel's drm/v3d driver scheduler timeout handlers could cause GPU hangs and UI freezes. The vulnerability arises because multiple hardware queues share a single global reset, but their timeout handlers run concurrently, leading to inconsistent scheduler state and credit mismanagement. This flaw can cause the GPU scheduler to have more credits in flight than allowed, resulting in a complete GPU hang. The issue has been resolved by serializing the timeout handlers using a shared ordered workqueue, preventing concurrent resets from interfering with each other.
