CVE-2026-72498

Kernel-address disclosure via RDMA MR dump

Published Aug 15, 2026 · Updated Aug 15, 2026

Information disclosure in the Linux bnxt_re driver allows local users to read a kernel address through an RDMA memory-region dump. The MR resource-dump path in drivers/infiniband/hw/bnxt_re/main.c places the mr_hwq kernel pointer in rdma tool output instead of omitting it. Access requires a local user able to query an MR through bnxt_re; the flaw exposes one kernel address rather than arbitrary kernel memory.
