{"id":"CVE-2026-64240","summary":"media: rc: igorplugusb: fix control request setup packet","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: rc: igorplugusb: fix control request setup packet\n\nCommit eac69475b01f (\"media: rc: igorplugusb: heed coherency\nrules\") changed the control request storage from an embedded struct to\nan allocated pointer so it can obey DMA coherency rules.\n\nHowever, the driver still passes &ir-\u003erequest to usb_fill_control_urb().\nThat points the URB setup packet at the pointer field itself rather than\nat the allocated struct usb_ctrlrequest.\n\nUSB core then interprets pointer bytes as the setup packet. This can\nproduce an invalid bRequestType and trigger the control direction warning\nreported by syzbot:\n\n  usb 2-1: BOGUS control dir, pipe 80003580 doesn't match bRequestType 0\n\nPass ir-\u003erequest itself as the setup packet.","modified":"2026-07-26T03:49:09.584173619Z","published":"2026-07-24T15:27:43.590Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64240.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/060fca8e098387f949e4eedaf215d952e477ac12"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0d880d2db9856e94127ab09331363bef59f98005"},{"type":"WEB","url":"https://git.kernel.org/stable/c/171022c7d594c133a45f92357a2a91475edabe20"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2243ad78ce64d344754260533ae7730c2174a34a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5cc3f6db72f77d1a8f7f1cf4ac01803927ffdf15"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aa22590a16e51455c6db802c774b31aadc604a9a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e823e4294511989f5962e7ad85bf4d179ba74f52"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f33b5a61673bd220fdaaf4202cf1013d6d66c943"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64240.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64240"},{"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":"bc04b8633b375af6ac8a8bb615258b80fe06cdaa"},{"fixed":"e823e4294511989f5962e7ad85bf4d179ba74f52"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"81f0fb813e4bf28b3ca28dc218938a32eb48f740"},{"fixed":"2243ad78ce64d344754260533ae7730c2174a34a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0e84aa8fc23c7578f105e3a2160f9d0aa2bed79a"},{"fixed":"aa22590a16e51455c6db802c774b31aadc604a9a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"18d6a7c9e4e63c57157e9a57dd9bf3cd38e4c45a"},{"fixed":"060fca8e098387f949e4eedaf215d952e477ac12"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0be8fcd9005e3d3b5a61fe34b070a9663adbb4dc"},{"fixed":"0d880d2db9856e94127ab09331363bef59f98005"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0adac0ee2c42027d80bac02ea9b576a88f8955d3"},{"fixed":"f33b5a61673bd220fdaaf4202cf1013d6d66c943"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"a62ca67e3c72fb297dc7c86495ba8f7329d7f150"},{"fixed":"5cc3f6db72f77d1a8f7f1cf4ac01803927ffdf15"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"eac69475b01fe1e861dfe3960b57fa95671c132e"},{"fixed":"171022c7d594c133a45f92357a2a91475edabe20"}]}],"versions":["v6.6.142","v6.6.141","v6.6.140","v6.12.92","v6.12.91","v6.12.90","v6.12.89","v6.12.88","v6.12.87","v6.12.86","v6.18.34","v6.18.33","v6.18.32","v6.18.31","v6.18.30","v6.18.29","v6.18.28","v6.18.27","v7.0.11","v7.0.10","v7.0.9","v7.0.8","v7.0.7","v7.0.6","v7.0.5","v7.0.4"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-64240.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.6.140"},{"fixed":"6.6.143"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.12.86"},{"fixed":"6.12.93"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.18.27"},{"fixed":"6.18.35"}]},{"type":"ECOSYSTEM","events":[{"introduced":"7.0.4"},{"fixed":"7.0.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-64240.json"}}],"schema_version":"1.7.5"}
