CVE-2023-45896
Published: August 30, 2024Last modified: June 17, 2025
Description
ntfs3 in the Linux kernel before 6.5.11 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.
