{"id":"CVE-2022-49051","summary":"net: usb: aqc111: Fix out-of-bounds accesses in RX fixup","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: usb: aqc111: Fix out-of-bounds accesses in RX fixup\n\naqc111_rx_fixup() contains several out-of-bounds accesses that can be\ntriggered by a malicious (or defective) USB device, in particular:\n\n - The metadata array (desc_offset..desc_offset+2*pkt_count) can be out of bounds,\n   causing OOB reads and (on big-endian systems) OOB endianness flips.\n - A packet can overlap the metadata array, causing a later OOB\n   endianness flip to corrupt data used by a cloned SKB that has already\n   been handed off into the network stack.\n - A packet SKB can be constructed whose tail is far beyond its end,\n   causing out-of-bounds heap data to be considered part of the SKB's\n   data.\n\nFound doing variant analysis. Tested it with another driver (ax88179_178a), since\nI don't have a aqc111 device to test it, but the code looks very similar.","modified":"2026-03-11T02:20:22.454875Z","published":"2025-02-26T01:54:25.850Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1194-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1263-1","SUSE-SU-2025:1293-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49051.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/36311fe98f55dea9200c69e2dd6d6ddb8fc94080"},{"type":"WEB","url":"https://git.kernel.org/stable/c/404998a137bcb8a926f7c949030afbe285472593"},{"type":"WEB","url":"https://git.kernel.org/stable/c/afb8e246527536848b9b4025b40e613edf776a9d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b416898442f2b6aa9f1b2f2968ce07e3abaa05f7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d90df6da50c56ad8b1a132e3cf86b6cdf8f507b7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49051.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49051"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"17364b805f5b9016bb528241ba91481e3497e5e1"},{"fixed":"404998a137bcb8a926f7c949030afbe285472593"},{"fixed":"d90df6da50c56ad8b1a132e3cf86b6cdf8f507b7"},{"fixed":"b416898442f2b6aa9f1b2f2968ce07e3abaa05f7"},{"fixed":"36311fe98f55dea9200c69e2dd6d6ddb8fc94080"},{"fixed":"afb8e246527536848b9b4025b40e613edf776a9d"}]}],"versions":["v4.20","v4.20-rc4","v4.20-rc5","v4.20-rc6","v4.20-rc7","v5.0","v5.0-rc1","v5.0-rc2","v5.0-rc3","v5.0-rc4","v5.0-rc5","v5.0-rc6","v5.0-rc7","v5.0-rc8","v5.1","v5.1-rc1","v5.1-rc2","v5.1-rc3","v5.1-rc4","v5.1-rc5","v5.1-rc6","v5.1-rc7","v5.10","v5.10-rc1","v5.10-rc2","v5.10-rc3","v5.10-rc4","v5.10-rc5","v5.10-rc6","v5.10-rc7","v5.10.1","v5.10.10","v5.10.100","v5.10.101","v5.10.102","v5.10.103","v5.10.104","v5.10.105","v5.10.106","v5.10.107","v5.10.108","v5.10.109","v5.10.11","v5.10.110","v5.10.111","v5.10.12","v5.10.13","v5.10.14","v5.10.15","v5.10.16","v5.10.17","v5.10.18","v5.10.19","v5.10.2","v5.10.20","v5.10.21","v5.10.22","v5.10.23","v5.10.24","v5.10.25","v5.10.26","v5.10.27","v5.10.28","v5.10.29","v5.10.3","v5.10.30","v5.10.31","v5.10.32","v5.10.33","v5.10.34","v5.10.35","v5.10.36","v5.10.37","v5.10.38","v5.10.39","v5.10.4","v5.10.40","v5.10.41","v5.10.42","v5.10.43","v5.10.44","v5.10.45","v5.10.46","v5.10.47","v5.10.48","v5.10.49","v5.10.5","v5.10.50","v5.10.51","v5.10.52","v5.10.53","v5.10.54","v5.10.55","v5.10.56","v5.10.57","v5.10.58","v5.10.59","v5.10.6","v5.10.60","v5.10.61","v5.10.62","v5.10.63","v5.10.64","v5.10.65","v5.10.66","v5.10.67","v5.10.68","v5.10.69","v5.10.7","v5.10.70","v5.10.71","v5.10.72","v5.10.73","v5.10.74","v5.10.75","v5.10.76","v5.10.77","v5.10.78","v5.10.79","v5.10.8","v5.10.80","v5.10.81","v5.10.82","v5.10.83","v5.10.84","v5.10.85","v5.10.86","v5.10.87","v5.10.88","v5.10.89","v5.10.9","v5.10.90","v5.10.91","v5.10.92","v5.10.93","v5.10.94","v5.10.95","v5.10.96","v5.10.97","v5.10.98","v5.10.99","v5.11","v5.11-rc1","v5.11-rc2","v5.11-rc3","v5.11-rc4","v5.11-rc5","v5.11-rc6","v5.11-rc7","v5.12","v5.12-rc1","v5.12-rc1-dontuse","v5.12-rc2","v5.12-rc3","v5.12-rc4","v5.12-rc5","v5.12-rc6","v5.12-rc7","v5.12-rc8","v5.13","v5.13-rc1","v5.13-rc2","v5.13-rc3","v5.13-rc4","v5.13-rc5","v5.13-rc6","v5.13-rc7","v5.14","v5.14-rc1","v5.14-rc2","v5.14-rc3","v5.14-rc4","v5.14-rc5","v5.14-rc6","v5.14-rc7","v5.15","v5.15-rc1","v5.15-rc2","v5.15-rc3","v5.15-rc4","v5.15-rc5","v5.15-rc6","v5.15-rc7","v5.15.1","v5.15.10","v5.15.11","v5.15.12","v5.15.13","v5.15.14","v5.15.15","v5.15.16","v5.15.17","v5.15.18","v5.15.19","v5.15.2","v5.15.20","v5.15.21","v5.15.22","v5.15.23","v5.15.24","v5.15.25","v5.15.26","v5.15.27","v5.15.28","v5.15.29","v5.15.3","v5.15.30","v5.15.31","v5.15.32","v5.15.33","v5.15.34","v5.15.4","v5.15.5","v5.15.6","v5.15.7","v5.15.8","v5.15.9","v5.16","v5.16-rc1","v5.16-rc2","v5.16-rc3","v5.16-rc4","v5.16-rc5","v5.16-rc6","v5.16-rc7","v5.16-rc8","v5.17","v5.17-rc1","v5.17-rc2","v5.17-rc3","v5.17-rc4","v5.17-rc5","v5.17-rc6","v5.17-rc7","v5.17-rc8","v5.17.1","v5.17.2","v5.17.3","v5.2","v5.2-rc1","v5.2-rc2","v5.2-rc3","v5.2-rc4","v5.2-rc5","v5.2-rc6","v5.2-rc7","v5.3","v5.3-rc1","v5.3-rc2","v5.3-rc3","v5.3-rc4","v5.3-rc5","v5.3-rc6","v5.3-rc7","v5.3-rc8","v5.4","v5.4-rc1","v5.4-rc2","v5.4-rc3","v5.4-rc4","v5.4-rc5","v5.4-rc6","v5.4-rc7","v5.4-rc8","v5.4.1","v5.4.10","v5.4.100","v5.4.101","v5.4.102","v5.4.103","v5.4.104","v5.4.105","v5.4.106","v5.4.107","v5.4.108","v5.4.109","v5.4.11","v5.4.110","v5.4.111","v5.4.112","v5.4.113","v5.4.114","v5.4.115","v5.4.116","v5.4.117","v5.4.118","v5.4.119","v5.4.12","v5.4.120","v5.4.121","v5.4.122","v5.4.123","v5.4.124","v5.4.125","v5.4.126","v5.4.127","v5.4.128","v5.4.129","v5.4.13","v5.4.130","v5.4.131","v5.4.132","v5.4.133","v5.4.134",
