In the Linux kernel, the following vulnerability has been resolved:

vme: Fix error not catched in fake_init()

In fake_init(), __root_device_register() is possible to fail but it's
ignored, which can cause unregistering vme_root fail when exit.

general protection fault,
probably for non-canonical address 0xdffffc000000008c
KASAN: null-ptr-deref in range [0x0000000000000460-0x0000000000000467]
