CVE-2026-22790

EVerest is an EV charging software stack. Prior to version 2026.02.0, `HomeplugMessage::setup_payload` 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.
