Description

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).

Affected configurations

• linux linux kernel (< 3.2.99) • linux linux kernel (>= 3.3 < 3.16.54) • linux linux kernel (>= 3.17 < 3.18.92) • linux linux kernel (>= 3.19 < 4.1.50) • linux linux kernel (>= 4.2 < 4.4.112) • linux linux kernel (>= 4.5 < 4.9.77) • linux linux kernel (>= 4.10 < 4.14.44) • debian debian linux 7.0 • debian debian linux 8.0 • canonical ubuntu linux 12.04 • canonical ubuntu linux 14.04 • canonical ubuntu linux 16.04 • canonical ubuntu linux 17.10
