Summary

The Linux kernel accel/amdxdna driver is affected from 6.14, with fixes in 7.2.7 and 7.3. Device buffers are never meant to be exported, but the driver did not explicitly disable exporting support, so buffers could be exported. The CVSS vector rates this as exploitable by a local user with low privileges, with high impact to confidentiality, integrity and availability.
