Summary
Multiple system services installed alongside the Razer Synapse 3 software suite perform privileged operations on entries within the Razer Chroma SDK subkey. These privileged operations consist of file name concatenation of a runtime log file that is used to store runtime log information. In other words, an attacker can create a file in an unintended directory (with some limitations).
Exploit prediction
0.50% chance of exploitation in the next 30 days, higher than 42% of all scored CVEs (FIRST EPSS, 2026-11-08).
