What is CVE-2023-45896?
CVE-2023-45896 is a high-severity vulnerability in n/a, published on 28 Aug 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
Weakness: CWE-276
