CVE-2026-64475

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> vfio/pci: Release the VGA arbiter client on register_device() failure<br /> <br /> The re-order in the Fixes commit below displaced vfio_pci_vga_init() as<br /> the last failure point of what is now vfio_pci_core_register_device()<br /> without introducing an unwind for the VGA arbiter registration.<br /> <br /> In current kernels this is mostly benign because vfio_pci_set_decode()<br /> only uses pci_dev state, but the original failure path could leave a<br /> callback with a freed vdev cookie. The stale registration also becomes<br /> unsafe again once the callback follows drvdata to the vfio device.<br /> <br /> Add the required VGA unwind callout.
