  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/vfio-ap: Fix control domain removal in vfio_ap_mdev_cfg_remove\n\nThe vfio_ap_config_remove function uses the bitmap_andnot function to clear\nbits from the matrix_mdev->matrix.adm bitmap (specifies the control domains\nassigned to the mdev). This prevents the explicitly unplugged control\ndomains from being removed the KVM guest. The bitmap_and function is used\ninstead.",
