Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: The issue is related to the iommufd access change ioas() function in the Linux kernel, which sets access->ioas to NULL during its process, potentially causing a lock to be gone in a concurrent racing context. This can lead to a general protection fault, probably for a non-canonical address. The problem is fixed by doing the same access->ioas sanity check as the iommufd access rw() and iommufd access pin pages() functions.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
