Last modified

CVE-2026-22790 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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. EPSS estimates a 0.53% chance of exploitation in the next 30 days.
