A malicious RDMA client can send usr_len > off causing\nan integer underflow, resulting in data_len wrapping to a huge size_t\nvalue which is then passed to the rdma_ev callback as a memory length,\nleading to out-of-bounds memory access.\n\nFix by reading and validating usr_len <= off before rtrs_srv_get_ops_ids()\nin both process_read() and process_write(), ensuring the early return\npath acquires no reference and has no resource leak.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
