CVE-2024-26977
Last modified
CVE-2024-26977 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
