CVE-2026-44104: Improper verification of cryptographic signature vulnerability

The firmware update process for the basemodule of the charging controller only validates the CRC32 checksum without cryptographic signature verification. This allows an unauthenticated remote attacker to install a modified firmware, resulting in full system compromise.
