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

Description A flaw exists in the Linux kernel related to a PCI device reference count leak within the mt7915 pci init hif2() function. The issue arises because the pci get device() function increments the reference count of a PCI device, and a corresponding pci dev put() call is missing to decrement the reference count. This can lead to a resource leak.

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