| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.8.0-rc7-gde77230ac23a
Description
The issue is related to the iommufd component in the Linux kernel, which requires drivers to supply the cache invalidate user ops. If drivers do not implement this operation, iommufd may encounter invalidation ioctls, resulting in a kernel NULL pointer dereference. The error is characterized by an Internal error: Oops message, followed by a call trace that includes the iommufd hwpt invalidate and iommufd fops ioctl functions. All existing drivers implement this op for nesting, and this fix is mostly a bisection aid.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
