CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.
