The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: vfio/mdev: Fix a null-ptr-deref bug     for mdev_unregister_parent() Inject fault while probing mdpy.ko, if kstrdup() of create_dir() fails in     kobject_add_internal() in kobject_init_and_add() in mdev_type_add() in parent_create_sysfs_files(), it     will return 0 and probe successfully. And when rmmod mdpy.ko, the mdpy_dev_exit() will call     mdev_unregister_parent(), the mdev_type_remove() may traverse uninitialized parent->types[i] in     parent_remove_sysfs_files(), and it will cause below null-ptr-deref. If mdev_type_add() fails, return the     error code and kset_unregister() to fix the issue. general protection fault, probably for non-canonical     address 0xdffffc0000000002: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range     [0x0000000000000010-0x0000000000000017] CPU: 2 PID: 10215 Comm: rmmod Tainted: G W N 6.6.0-rc2+ #20     Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 RIP:
