CVE-2026-46314
Description
A flaw was found in the Linux kernel's drm/v3d component. A local user can exploit this vulnerability by crafting a self-referential multisync extension with zero synchronization counts. This bypasses existing guards, leading to an infinite loop within the kernel. The consequence is a Denial of Service (DoS), where the affected system's CPU core is indefinitely consumed, blocking the calling thread.
