What is CVE-2025-68136?
CVE-2025-68136 is a high-severity denial of service vulnerability in everest-core, published on 21 Jan 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
EVerest is an EV charging software stack. Prior to version 2025.10.0, once the module receives a SDP request, it creates a whole new set of objects like `Session`, `IConnection` which open new TCP socket for the ISO15118-20 communications and registers callbacks for the created file descriptor, without closing and destroying the previous ones. Previous `Session` is not saved and the usage of an `unique_ptr` is lost, destroying connection data. Latter, if the used socket and therefore file descriptor is not the last one, it will lead to a null pointer dereference. Version 2025.10.0 fixes the issue.
Weakness: CWE-770
