CVE-2018-20511 (retired)

Priority
Description
An issue was discovered in the Linux kernel before 4.18.11. The ipddp_ioctl
function in drivers/net/appletalk/ipddp.c allows local users to obtain
sensitive kernel address information by leveraging CAP_NET_ADMIN to read
the ipddp_route dev and next fields via an SIOCFINDIPDDPRT ioctl call.
Ubuntu-Description
It was discovered that the Appletalk IP encapsulation driver in the Linux
kernel did not properly prevent kernel addresses from being copied to user
space. A local attacker with the CAP_NET_ADMIN capability could use this to
expose sensitive information.
Notes
tyhicksAn attacker needs root privileges (the CAP_NET_ADMIN capability) to
leverage this flaw.
