MEDIUM

Linux kernel - Buffer Overflow

Title source: llm

Description

In the Linux kernel, the following vulnerability has been resolved: pci_iounmap(): Fix MMIO mapping leak The #ifdef ARCH_HAS_GENERIC_IOPORT_MAP accidentally also guards iounmap(), which means MMIO mappings are leaked. Move the guard so we call iounmap() for MMIO mappings.
