However, that might happen\nbefore the usb hub_event handler is able to notify the driver. This\npatch adds a sanity check before the invalid read reported by syzbot,\nwithin the context disconnection call stack." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "Linux", "product": { "product_data": [ { "product_name": "Linux", "version": { "version_data": [ { "version_affected": "<", "version_name": "e5be15c63804", "version_value": "ec36c134dd02" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "2.6.26", "status": "affected" }, { "version": "0", "lessThan": "2.6.26", "status": "unaffected", "versionType": "semver" }, { "version": "4.19.306", "lessThanOrEqual": "4.19.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.4.268", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.209", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.148", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.75", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.14", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.7.2", "lessThanOrEqual": "6.7.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/ec36c134dd020d28e312c2f1766f85525e747aab", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/ec36c134dd020d28e312c2f1766f85525e747aab" }, { "url": "https://git.kernel.org/stable/c/47aa8fcd5e8b5563af4042a00f25ba89bef8f33d", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/47aa8fcd5e8b5563af4042a00f25ba89bef8f33d" }, { "url": "https://git.kernel.org/stable/c/3233d8bf7893550045682192cb227af7fa3defeb", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/3233d8bf7893550045682192cb227af7fa3defeb" }, { "url": "https://git.kernel.org/stable/c/ec3634ebe23fc3c44ebc67c6d25917300bc68c08", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/ec3634ebe23fc3c44ebc67c6d25917300bc68c08" }, { "url": "https://git.kernel.org/stable/c/30773ea47d41773f9611ffb4ebc9bda9d19a9e7e", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/30773ea47d41773f9611ffb4ebc9bda9d19a9e7e" }, { "url": "https://git.kernel.org/stable/c/2cf0005d315549b8d2b940ff96a66c2a889aa795", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/2cf0005d315549b8d2b940ff96a66c2a889aa795" }, { "url": "https://git.kernel.org/stable/c/437b5f57732bb4cc32cc9f8895d2010ee9ff521c", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/437b5f57732bb4cc32cc9f8895d2010ee9ff521c" }, { "url": "https://git.kernel.org/stable/c/ded85b0c0edd8f45fec88783d7555a5b982449c1", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/ded85b0c0edd8f45fec88783d7555a5b982449c1" } ] }, "generator": { "engine": "bippy-9e1c9544281a" } }
