The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.9.8 does not properly validate meta block groups, which allows physically proximate attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image.

MEDIUM6.5
The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel through 4.9.8 improperly emulates the VMXON instruction, which allows KVM L1 guest OS users to cause a denial of service (host OS memory consumption) by leveraging the mishandling of page references.

MEDIUM5.5
drivers/hid/hid-cp2112.c in the Linux kernel 4.9.x before 4.9.9 uses a spinlock without considering that sleeping is possible in a USB HID request callback, which allows local users to cause a denial of service (deadlock) via unspecified vectors.

HIGH7.8
The cp2112_gpio_direction_input function in drivers/hid/hid-cp2112.c in the Linux kernel 4.9.x before 4.9.9 does not have the expected EIO error status for a zero-length report, which allows local users to have an unspecified impact via unknown vectors.
