AI-suggested
A fix is available and has been applied in specific Linux kernel commits. Users and administrators should update to a Linux kernel version that includes these fixes to ensure the vm_bind range overlap check is enforced. No additional mitigation is required beyond applying the official patch.
Description
A vulnerability in the Linux kernel's drm/panthor component was fixed by adding a check to prevent vm_bind mappings from overlapping with the kernel BO address space range. This flaw allowed vm_bind mappings of user-exposed buffer objects to intersect with reserved kernel address space, which was previously unchecked. The fix also ensures that vm_bind ranges do not overflow 64-bit unsigned integer limits, improving early validation and resource allocation efficiency.
