CVE-2026-80620

A flaw was found in the Linux kernel. During the error handling of Message Signaled Interrupts eXtended MSI-X region setup, the kernel attempts to unmap an already freed memory region. This double unmap operation on a null pointer can lead to a kernel warning or crash. A local attacker could...

CVE-2026-80620

CVE-2026-80620 is a Linux kernel vulnerability in the PCI/MSI subsystem . A prior commit (1a8d4c6ecb4c) added an iounmap(dev->msix_base) on the error path of msix_capability_init(), but pci_free_msi_irqs() — called earlier via the __free(free_msi_irqs) cleanup — already unmapped the region and...
