Name of the Vulnerable Software and Affected Versions Linux Kernel versions prior to v5.4.198

Description The issue is related to a potential deadlock in the Linux Kernel, specifically with the pci dev lock() function and sriov numvfs store(). The actual impact and attack plausibility have not yet been proven.

Recommendations For Linux Kernel versions prior to v5.4.198, update to version v5.4.198 or later to resolve the issue. As a temporary workaround, consider avoiding the use of sriov numvfs store() to minimize the risk of deadlock.
