CVE-2026-79602
A flaw was found in Xen. A malicious guest operating system, when configured with a PCI device that has a Base Address Register BAR mapped to the I/O port space, can trigger an internal error within the Xen hypervisor. This vulnerability could lead to a denial of service, causing the host system ...
SUSE CVE-2026-80821
In the Linux kernel, the following vulnerability has been resolved: nvmet: pci-epf: put CQ ref on createcq mapping failure nvmetpciepfcreatecq calls nvmetcqcreate, which takes a reference on the controller and installs the completion queue. If the subsequent PCI address-space mapping fails or...

DEBIAN-CVE-2026-62437
When guests are terminated, various pieces of cleanup need carrying out. The cleaning up of PCI devices which were assigned to guests, and the associated removal of tracking structures for IRQs used by the devices occurs relatively early in the process. Unfortunately after that point the guest...

kernel: vfio/pci: Clean up DMABUFs before disabling function
A flaw was found in the Linux kernel's vfio/pci subsystem. During device shutdown, an improper order of operations in cleaning up Direct Memory Access Buffers DMABUFs before disabling the function creates a brief window. In this window, a device's Base Address Registers BARs could still be access...
kernel: vfio/pci: Check BAR resources before exporting a DMABUF
A flaw was found in the Linux kernel's vfio/pci subsystem. This vulnerability occurs because the Direct Memory Access Buffer DMABUF export mechanism does not adequately verify if Base Address Register BAR resources are properly reserved before allowing access. A local attacker could exploit this ...

CVE-2026-79602
A flaw exists in the Xen hypervisor where a malicious guest operating system with an assigned PCI device featuring a Base Address Register (BAR) mapped to the I/O port space can trigger an internal BUG() . This vulnerability is caused by the improper handling of HVM emulation return codes . The i...
