According\nto RCU usage rules, this is illegal and can lead to unpredictable\nbehavior, such as accessing memory that has been updated or causing\nuse-after-free issues.\n\nThis possible bug was identified using a static analysis tool developed\nby myself, specifically designed to detect RCU-related issues.\n\nTo address this, the `scan_req->type` value is now stored in a local\nvariable `scan_req_type` while still within the RCU read-side critical\nsection. The `scan_req_type` is then used after the RCU lock is released,\nensuring that the type value is safely accessed without violating RCU\nrules." } ] }, "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": "e2c3e6f53a7a", "version_value": "e676e4ea76bb" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "6.5", "status": "affected" }, { "version": "0", "lessThan": "6.5", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.55", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10.14", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.3", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/e676e4ea76bbe7f1156d8c326b9b6753849481c2", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/e676e4ea76bbe7f1156d8c326b9b6753849481c2" }, { "url": "https://git.kernel.org/stable/c/540138377b22f601f06f55ebfa3ca171dcab471a", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/540138377b22f601f06f55ebfa3ca171dcab471a" }, { "url": "https://git.kernel.org/stable/c/d18f669461811dfe2915d5554ab2a9834f810013", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/d18f669461811dfe2915d5554ab2a9834f810013" }, { "url": "https://git.kernel.org/stable/c/bff1709b3980bd7f80be6786f64cc9a9ee9e56da", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/bff1709b3980bd7f80be6786f64cc9a9ee9e56da" } ] }, "generator": { "engine": "bippy-8e903de6a542" } }
