kernel: net/packet: slab-out-of-bounds access in packet_recvmsg()

An out-of-bounds access issue was found in the Linux kernel networking subsystem in the way raw packet sockets AFPACKET used PACKETCOPYTHRESH and mmap operations. A local attacker with CAPNETRAW capability could use this flaw to trigger a buffer overflow resulting in a system crash or privilege...
