{"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":"2026-04-02T08:27:15.559959Z","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":"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"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"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"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49051.json"}}],"schema_version":"1.7.5"}
