In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
RDMA\/bng_re: return a timeout when firmware responses stall<\/p>\n
__wait_for_resp() documents that it returns a non-zero error when a
\nfirmware command does not complete, and bng_re_rcfw_send_message() already
\nmarks the firmware as stalled when the helper returns -ENODEV.<\/p>\n
However, the helper ignores wait_event_timeout() expiry. If the response
\nslot remains in use after the timeout and after the polled CREQ service
\nattempt, the loop starts another full timeout period and can repeat
\nforever.<\/p>\n
Return -ENODEV after a timed out wait that still has no response. The
\nexisting caller then marks FIRMWARE_STALL_DETECTED and returns
\n-ETIMEDOUT to the command issuer.<\/p>\n","protected":false},"excerpt":{"rendered":"
