CVE-2018-5332

Published: 11 January 2018

In the Linux kernel through 3.2, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c).

From the Ubuntu security team

It was discovered that the Reliable Datagram Socket (RDS) implementation in the Linux kernel contained an out-of-bounds write during RDMA page allocation. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

Priority

Medium

CVSS 3 base score: 7.8
