This restriction needs to apply regardless of whether the cycle\ntime came from the user or was the implicit, auto-calculated value, so\nwe move the existing \"cycle == 0\" check outside the \"if \"(!new->cycle_time)\"\nbranch. This way covers both conditions and scenarios.\n\nAdd a selftest which illustrates the issue triggered by syzbot." } ] }, "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": "b5b73b26b3ca", "version_value": "b939d1e04a90" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "5.9", "status": "affected" }, { "version": "0", "lessThan": "5.9", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.33", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9.4", "lessThanOrEqual": "6.9.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/b939d1e04a90248b4cdf417b0969c270ceb992b2", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/b939d1e04a90248b4cdf417b0969c270ceb992b2" }, { "url": "https://git.kernel.org/stable/c/91f249b01fe490fce11fbb4307952ca8cce78724", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/91f249b01fe490fce11fbb4307952ca8cce78724" }, { "url": "https://git.kernel.org/stable/c/fb66df20a7201e60f2b13d7f95d031b31a8831d3", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/fb66df20a7201e60f2b13d7f95d031b31a8831d3" } ] }, "generator": { "engine": "bippy-9e1c9544281a" } }
