Later\nsq_wr_avail accounting in srpt_queue_response() or srpt_write_pending()\ncan then subtract the wrong number of send queue credits.\n\nReset the counters and clear rw_ctxs after freeing the heap\nallocation before returning an error.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
