Hence add such checking to fix the problem.\n\nAlso fix similar problem in choose_slow_rdev()." } ] }, "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": "9f3ced792203", "version_value": "2febf5fdbf5d" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "6.9", "status": "affected" }, { "version": "0", "lessThan": "6.9", "status": "unaffected", "versionType": "semver" }, { "version": "6.10.7", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/2febf5fdbf5d9a52ddc3e986971c8609b1582d67", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/2febf5fdbf5d9a52ddc3e986971c8609b1582d67" }, { "url": "https://git.kernel.org/stable/c/c916ca35308d3187c9928664f9be249b22a3a701", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/c916ca35308d3187c9928664f9be249b22a3a701" } ] }, "generator": { "engine": "bippy-9e1c9544281a" } }
