Summary

The Linux kernel drm/imagination driver is affected from 6.8. The firmware reconstruction count is not bounded to the size of the request's fixed freelist ID array or the fixed response array, so accesses can run past those arrays. The fix clamps the count to the request capacity and uses that clamped value for both reconstruction and response publication.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: clamp freelist reconstruction requests The firmware reconstruction count controls accesses to the request's fixed freelist ID array and the copy into the fixed response array. Neither access currently bounds the count to those protocol arrays. Clamp the count to the request capacity, which is shared by the response layout, and use that count consistently for reconstruction and response publication. Keep the firmware recovery exchange instead of dropping an oversized request without a response, as discussed with the firmware maintainer. The issue was found by our static-analysis tool.
