Stack-based buffer overflow in XCharge C6

Published May 28, 2026 CVSS 4.0 · 8.6 High EPSS < 1% KEV · Not listed
Description
A stack-based buffer overflow vulnerability in the charging controller’s signal-processing logic allows an attacker with physical access to the charging interface to supply message fields that exceed expected bounds.
