CVE-2024-57936Network attack vector

Kernel memory corruption via oversized RDMA work requests

Published Jan 21, 2025 · Updated Aug 5, 2026

Out-of-bounds stack write in the Linux kernel bnxt_re driver 6.12 through 6.12.8 allows remote attackers to corrupt memory via RDMA I/O. The driver advertises 13 send SGEs on Gen P7 hardware while its WQE stack array holds six, so a work request with at least seven entries writes beyond the array. Reachability requires a bnxt_re-backed RDMA endpoint or local uverbs access; corruption can disclose kernel data, alter kernel memory, or crash the system.
