Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A memory leak exists in the vfio ap device driver within the Linux kernel. The device release callback function incorrectly attempts to free memory associated with a vfio matrix dev object. Specifically, the
dev get drvdata(device *dev) function does not retrieve the correct pointer to the object, resulting in the memory not being freed. The kfree function handles the NULL pointer gracefully, preventing a crash, but leaving the memory allocated. The affected component is the vfio ap device driver.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
