Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A NULL pointer dereference issue has been resolved in the Linux kernel, specifically in the uio hv generic module. The issue occurs when the primary channel pointer is NULL for primary VM Bus channels, as this pointer is only valid for secondary channels. The rescind callback is meant for primary channels only. The fix involves retrieving the device obj from the parent for the primary channel to prevent the NULL pointer dereference.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
