kernel: vhost-net: stack overflow in get_raw_socket while checking sk_family field

A stack buffer overflow issue was found in the getrawsocket routine of the Host kernel accelerator for virtio net vhost-net driver. It could occur while doing an ictolVHOSTNETSETBACKEND call, and retrieving socket name in a kernel stack variable via getrawsocket. A user able to perform ioctl2 cal...

Kernel: kvm: OOB memory write via kvm_dev_ioctl_get_cpuid

An out-of-bounds memory write issue was found in the way the Linux kernel's KVM hypervisor handled the 'KVMGETEMULATEDCPUID' ioctl2 request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulti...
