CVE-2024-35902

Local service crash via unchecked connection pointer

Published May 19, 2024 · Updated May 23, 2026

NULL pointer dereference in Linux kernel RDS RDMA mapping allows local users to crash the system through a failed memory-region request. The __rds_rdma_map function handles an error pointer from rds_ib_get_mr but dereferences cp->cp_conn without first rejecting a NULL cp argument. Exploitation requires local low-privileged access and a configured RDS over InfiniBand path; the demonstrated consequence is a kernel crash only.
