The vulnerability of the vfiopci_core_feature_dma_buf() function in the driver/vfio/pci/vfiopci_dmabuf.c file of the VFIO device drivers for the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the vfiopcicorefeaturedmabuf function in the driver/vfio/pci/vfiopcidmabuf.c file of the VFIO device drivers in the Linux operating system is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the...

CVE-2026-64476

A flaw was found in the Linux kernel's vfio/pci driver. The disableidled3 flag, which controls device power states, was handled as a global module parameter instead of being latched per device. This improper handling could lead to unbalanced Power Management PM operations for devices already boun...
