CVE-2026-64020

A flaw was found in the Linux kernel's nvme-pci driver. This vulnerability occurs due to improper handling of peer-to-peer P2P memory, where dmavec allocations are not correctly unmapped. This oversight leads to a memory leak, which can degrade system performance and potentially lead to a denial ...

The vulnerability of the pci_register_host_bridge() function in the drivers/pci/probe.c module of the Linux system’s PCI device driver allows a hacker to cause a service failure.

The vulnerability of the pciregisterhostbridge function in the drivers/pci/probe.c file of the Linux PCI device driver module is related to improper memory release memory leak. Exploiting this vulnerability could allow an attacker to cause a system failure...
