Prior to version 0.10.2, the heap initialization methods were missing a minimum size check for the given heap size argument. This could lead to out-of-bound writes when a heap was initialized with a size smaller than `3 * size_of::<usize>` because of metadata write operations. This vulnerability impacts all the initialization functions on the `Heap` and `LockedHeap` types, including `Heap::new`, `Heap::init`, `Heap::init_from_slice`, and `LockedHeap::new`. It also affects multiple uses of the `Heap::extend` method. Version 0.10.2 contains a patch for the issue. As a workaround, ensure that the heap is only initialized with a size larger than `3 * size_of::<usize>` and that the `Heap::extend` method is only called with sizes larger than `2 * size_of::<usize>()`. Also, ensure that the total heap size is (and stays) a multiple of `2 * size_of::<usize>()`.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2022-09-07 23:15:00","updated_at":"2023-07-21 19:23:00"},"problem_types":["CWE-1284"],"metrics":[],"references":[{"url":"https://github.com/rust-osdev/linked-list-allocator/security/advisories/GHSA-xg8p-34w2-j49j","name":"https://github.com/rust-osdev/linked-list-allocator/security/advisories/GHSA-xg8p-34w2-j49j","refsource":"CONFIRM","tags":[],"title":"Out-of-bound writes possible on `Heap` initialization and `Heap::extend` · Advisory · rust-osdev/linked-list-allocator · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/rust-osdev/linked-list-allocator/commit/013b0758643943e8df5b17bbb495460ff47e8bbf","name":"https://github.com/rust-osdev/linked-list-allocator/commit/013b0758643943e8df5b17bbb495460ff47e8bbf","refsource":"MISC","tags":[],"title":"Merge pull request from GHSA-xg8p-34w2-j49j · rust-osdev/linked-list-allocator@013b075 · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-36086","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36086","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"36086","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"rust-osdev","cpe5":"linked-list-allocator","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"rust","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2022-36086","STATE":"PUBLIC","TITLE":"linked_list_allocator vulnerable to out-of-bound writes on `Heap` initialization and `Heap::extend`"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"linked-list-allocator","version":{"version_data":[{"version_value":"< 0.10.2"}]}}]},"vendor_name":"rust-osdev"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"linked_list_allocator is an allocator usable for no_std systems.
