Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A refcount leak issue in the Linux kernel has been identified and resolved. The problem occurs in the
nv1a ram new() function, where a PCI device reference count is not properly decremented after use. According to the comment for pci get domain bus and slot(), this function returns a PCI device with an incremented reference count, and the caller is responsible for decrementing the count by calling pci dev put() when finished using the device. This issue can be avoided by calling pci dev put() after using the PCI device.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
