CVE-2024-26977
Assigner: Linux
Published: 2024-05-01T05:20:28.830Z
State: PUBLISHED
descriptions: value: 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.
