Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a NULL pointer dereference that can occur due to race conditions involving the adminq in the pds core module of the Linux kernel. This happens when the device goes through a reset via PCIe reset and/or a fw down/fw up cycle due to bad PCIe state or bad device state, causing the adminq to be destroyed and recreated. To fix this, further state checks and reference counting for adminq uses have been implemented. The reference counting is used because multiple threads can attempt to access the adminq at the same time, and multiple clients can be using it simultaneously.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
