CVE-2026-74377: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Copy WQE to local buffer in non-SRQ receive path For non-SRQ QPs, the responder reads WQE fields directly from the shared queue buffer mapped into userspace. This allows a malicious user to modify fields like numsge or...
