What is CVE-2026-2541?
CVE-2026-2541 is a medium-severity vulnerability in Micca Auto Electronics Co., Ltd. Car Alarm System KE700, published on 15 Feb 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The Micca KE700 system relies on a 6-bit portion of an identifier for authentication within rolling codes, providing only 64 possible combinations.
