A double free bug in packet_set_ring() in net/packet/af_packet.c can be exploited by a local user through crafted syscalls to escalate privileges or deny service. We recommend upgrading kernel past the effected versions or rebuilding past ec6af094ea28f0f2dda1a6a33b14cd57e36a9755
A double-free flaw was found in the Linux kernel’s packet protocol subsystem in the way a user call triggers the packet_set_ring() function of the net/packet/af_packet.c. This flaw allows a local user to crash or escalate their privileges on the system.
