CVE-2026-74389

Summary: CVE-2026-74389 affects the Linux kernel RDMA driver for HNS (hns_roce). When hns_roce_cmd_mbox() fails, the error path could flood logs due to unlimited ibdev_err/ibdev_warn outputs, potentially leading to a system crash. The fix replaces the non-limited error prints with ratelimited ver...

CVE-2026-72045

CVE-2026-72045 : In the Linux kernel (octeontx2-af: cn10k), a VF could access another function’s LMTLINE via rvu_mbox_handler_lmtst_tbl_setup() using base_pcifunc as a direct index into the LMT map. The issue arises because base_pcifunc is not sanitized and is not bounded to the VF’s PF, allowing...
