CVE-2026-22790: EVerest's unchecked SLAC payload length causes stack overflow in HomeplugMessage::setup_payload
EVerest is an EV charging software stack. Prior to version 2026.02.0, HomeplugMessage::setuppayload trusts len after an assert; in release builds the check is removed, so oversized SLAC payloads are memcpy'd into a ~1497-byte stack buffer, corrupting the stack and enabling remote code execution from network-provided frames. Version 2026.02.0 contains a patch.
