A flaw was found in the svcrdma component of the Linux kernel. Incorrect offset arithmetic in the svc_rdma_read_chunk_range() function can lead to a u32 underflow. This underflow can cause the system to attempt to allocate a large amount of memory, potentially resulting in a Denial of Service (DoS) due to excessive memory consumption.
