A flaw was found in the svcrdma component of the Linux kernel. A remote attacker can exploit this vulnerability by supplying a crafted RPC/RDMA Read chunk position field that is not properly validated against the received inline body length. This can lead to an underflow, exposing adjacent slab memory or allowing data to be copied past the receive buffer into request pages. The most significant impact is information disclosure, potentially leading to memory corruption.
