CVE-2018-5333
Published: 11 January 2018
In the Linux kernel through 4.14.13, the rds_cmsg_atomic function in net/rds/rdma.c mishandles cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference.
From the Ubuntu Security Team
Mohamed Ghannam discovered a null pointer dereference in the RDS (Reliable Datagram Sockets) protocol implementation of the Linux kernel. A local attacker could use this to cause a denial of service (system crash).
