CVE-2024-26977

CVE-2024-26977 — Linux kernel MMIO leak due to broken guarding of iounmap(). The vulnerability arises because the ARCH_HAS_GENERIC_IOPORT_MAP guard was applied to iounmap() in pci_iounmap(), causing MMIO mappings to leak. The fix relocates the guard so iounmap() is called for MMIO mappings, preve...

CVE-2024-26975

CVE-2024-26975 affects the Linux kernel powercap/intel_rapl MMIO RAPL path. A NULL pointer dereference occurs when probing intel_rapl on platforms whose CPU ID is not in intel_rapl_common’s model list, because defaults_msr may be uninitialized after the cited commit. The fix adds a sanity check t...
