Technical Description
In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Disallow re-exporting imported GEM objects
Prevent re-exporting of imported GEM buffers by adding a custom
prime_handle_to_fd callback that checks if the object is imported
and returns -EOPNOTSUPP if so.
Re-exporting imported GEM buffers causes loss of buffer flags settings,
leading to incorrect device access and data corruption.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
