CVE-2026-27828

5.5 mediumEPSS 0.3%

Medium (5.5) in linuxfoundation everest. EPSS 0.3% chance of exploitation in the next 30 days.

EVerest is an EV charging software stack. Prior to version 2026.02.0, ISO15118_chargerImpl::handle_session_setup uses v2g_ctx after it has been freed when ISO15118 initialization fails (e.g., no IPv6 link-local address). The EVSE process can be crashed remotely by an attacker with MQTT access who issues a session_setup command while v2g_ctx has been released. Version 2026.02.0 contains a patch.
