What is CVE-2023-29146?
CVE-2023-29146 is a high-severity vulnerability in n/a, published on 9 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The utility functions used by Malwarebytes EDR 1.0.11 on Linux for calculating a cryptographic hash of data bytes truncate the hashed data if it exceeds 4GB. This leads to an integer wrap-around if the data is larger than the maximum unsigned integer value (32-bit). Attackers could create a colliding hash value for two different strings by attaching 4GB of data to a string that is less than 4GB in size.
Weakness: CWE-190
