The\ngeneric length check only rejects zero-length and oversized skbs, so\na short monitor frame can be read past the end of the skb data.\n\nRequire enough bytes for the radiotap TX header and the destination\naddress field before using the monitor-mode header layout.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
