Overview
CVE-2026-93153 is a known-severity vulnerability. It was published on September 17, 2026.
Technical description
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.
