CVE-2026-64102

A flaw was found in the Linux kernel's Soft-iWARP siw component for Remote Direct Memory Access RDMA. A remote attacker can send a specially crafted iWARP Fast Path Data Unit FPDU with a manipulated length field. This manipulation causes an integer underflow, leading to a use-after-free...

CVE-2026-64102 RDMA/siw: Reject MPA FPDU length underflow before signed receive math

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Reject MPA FPDU length underflow before signed receive math A malicious connected siw peer can send an iWARP FPDU whose MPA length field chdr-mpalen, 16 bit big-endian, peer-controlled is smaller than the fixed DDP/RDMA...
