In the Linux kernel, the following vulnerability has been resolved: vfio/pci: fixed a memory leak during the transition from D3hot to D0 If the variable ‘vfiopcicoredevice::needspmrestore’ is set i.e., the PCI device does not have the NoSoftReset bit set in its PMCSR configuration register, then...

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 deficiencies in access control. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...

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 ...
