FKIE_CVE-2026-22790

Vulnerability from fkie_nvd - Published: 2026-03-26 15:16 - Updated: 2026-06-17 10:20
Severity
8.8 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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.
