CVE-2026-22790 PUBLISHED

EVerest's unchecked SLAC payload length causes stack overflow in HomeplugMessage::setup_payload

Assigner: GitHub_M
Reserved: 09.01.2026 Published: 26.03.2026 Updated: 26.03.2026

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.
