Linux kernel is vulnerable to Out-of-Bounds Write. This is possible due to improper validation of certain block-size data in the packet_set_ring() function of the Linux kernel’s networking implementation. Local users with CAP_NET_RAW capability could possibly cause a denial of service condition via crafted system calls.
