Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to a memory leak in the pci iounmap() function. The #ifdef ARCH HAS GENERIC IOPORT MAP guard accidentally also guards iounmap(), resulting in MMIO mappings being leaked. To fix this, the guard needs to be moved so that iounmap() is called for MMIO mappings. This could potentially allow an attacker to cause a denial of service.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
