Descriptions

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.

En el kernel de Linux hasta la versión 4.14.13, la función rds_cmsg_atomic en net/rds/rdma.c gestiona de manera incorrecta los casos en los que fracasa la asignación de páginas o cuando se proporciona una dirección no válida, lo que conduce a una desreferencia de puntero NULL en rds_atomic_free_op.

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 by a user. This can lead to a NULL pointer dereference in rds_atomic_free_op() and thus to a system panic.
