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.
