{"id":"CVE-2023-45896","details":"ntfs3 in the Linux kernel through 6.8.0 allows a physically proximate attacker to read kernel memory by mounting a filesystem (e.g., if a Linux distribution is configured to allow unprivileged mounts of removable media) and then leveraging local access to trigger an out-of-bounds read. A length value can be larger than the amount of memory allocated. NOTE: the supplier's perspective is that there is no vulnerability when an attack requires an attacker-modified filesystem image.","modified":"2026-05-12T04:12:21.675934Z","published":"2024-08-28T00:00:00Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45896.json","cna_assigner":"mitre"},"references":[{"type":"WEB","url":"https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.5.11"},{"type":"WEB","url":"https://dfir.ru/2024/06/19/vulnerabilities-in-7-zip-and-ntfs3/"},{"type":"WEB","url":"https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=013ff63b649475f0ee134e2c8d0c8e65284ede50"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45896.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-45896"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/013ff63b649475f0ee134e2c8d0c8e65284ede50"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git","events":[{"introduced":"0"},{"fixed":"013ff63b649475f0ee134e2c8d0c8e65284ede50"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-45896.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/torvalds/linux","events":[{"introduced":"0"},{"fixed":"013ff63b649475f0ee134e2c8d0c8e65284ede50"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-45896.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H"}]}
