CVE-2019-16714

Priority
Description
In the Linux kernel before 5.2.14, rds6_inc_info_copy in net/rds/recv.c
allows attackers to obtain sensitive information from kernel stack memory
because tos and flags fields are not initialized.
Ubuntu-Description
It was discovered that the IPv6 RDS implementation in the Linux kernel did
not properly initialize fields in a data structure returned to user space.
A local attacker could use this to expose sensitive information (kernel
memory). Please note that the RDS protocol is blacklisted in Ubuntu by
default.
Mitigation
Ensure that /etc/modprobe.d/blacklist-rare-network.conf contains the following
lines:
# rds
alias net-pf-21 off
Notes
tyhicksThis is a local info leak that is only reachable by calling the
getsockopt(2) system call on an IPv6 RDS socket.
By default, the rds.ko module is blacklisted in Ubuntu 14.04 LTS and
newer releases.
