Descriptions
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).
En el kernel de Linux hasta la versión 3.2, la función rds_message_alloc_sgs() no valida un valor empleado durante la asignación de página DMA, lo que conduce a una escritura fuera de límites basada en memoria dinámica (heap), relacionado con la función rds_rdma_extra_size en net/rds/rdma.c
In the Linux kernel through 4.14.13, 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') and thus to a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
