CVE-2018-5332
First published: Thu Jan 11 2018(Updated: )
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).
