CVE-2026-93153
In the Linux kernel, the following vulnerability has been resolved: RDMA/bng_re: return a timeout when firmware responses stall __wait_for_resp() documents that it returns a non-zero error when a firmware command does not complete, and bng_re_rcfw_send_message() already marks the firmware as stalled when the helper returns -ENODEV. However, the helper ignores wait_event_timeout() expiry. If the response slot remains in use after the timeout and after the polled CREQ service attempt, the loop starts another full timeout period and can repeat forever. Return -ENODEV after a timed out wait that still has no response. The existing caller then marks FIRMWARE_STALL_DETECTED and returns -ETIMEDOUT to the command issuer.
