A race condition vulnerability in the Linux kernel's Direct Rendering Manager (DRM) Graphics Execution Manager (GEM) subsystem was resolved. The issue involved a timing window where the old handle remained live in the IDR (ID Radix tree) after releasing a lock, allowing a concurrent deletion to free the GEM object while still referenced by a new handle. This could lead to use-after-free conditions. The fix nullifies the old handle's IDR entry before releasing the lock to prevent concurrent operations from accessing freed memory.
