For those issues to happen, a malformed\nwire message is needed to be sent from the device.\n\nInstead of duplicating the bounds checking code already present in\ndecode_message(), use the function inside resp_worker().","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
