- accel/ivpu: Disallow re-exporting imported GEM objects
- Details
-
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 primehandleto_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.
