What is CVE-2025-10937?
CVE-2025-10937 is a medium-severity denial of service vulnerability in Oxford Nano Technologies MinKNOW, published on 23 Oct 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Oxford Nanopore Technologies' MinKNOW software at or prior to version 24.11 creates a temporary file to store the local authentication token during startup, before copying it to its final location. This temporary file is created in a directory accessible to all users on the system. An unauthorized local user or process can exploit this behavior by placing a file lock on the temporary token file using the flock system call. This prevents MinKNOW from completing the token generation process. As a result, no valid local token is created, and the software is unable to execute commands on the sequencer. This leads to a denial-of-service (DoS) condition, blocking sequencing operations.
Weakness: CWE-754
