Linux Kernel Vulnerability in DRM/XE Driver by The Linux Foundation

CVE-2026-46264

What is CVE-2026-46264?

A flaw in the DRM/XE driver's sysfs initialization process can lead to uninitialized kobject errors when the cleanup action is invoked due to devm_add_action_or_reset() failure. This situation can result in warnings related to uninitialized kobjects and refcount underflows, which could compromise system stability. The issue has been addressed by modifying the initialization sequence to ensure proper kobject setup before cleanup registrations are invoked.
