CVE-2026-23955: Linuxfoundation Everest

Medium severity, CVSS 4.2. EPSS: 0.2% chance of exploitation in the next 30 days.

EVerest is an EV charging software stack. Prior to version 2025.9.0, in several places, integer values are concatenated to literal strings when throwing errors. This results in pointers arithmetic instead of printing the integer value as expected, like most of interpreted languages. This can be used by malicious operator to read unintended memory regions, including the heap and the stack. Version 2025.9.0 fixes the issue.

Affected products

• Linuxfoundation Everest: before 2025.9.0 (fixed in 2025.9.0)
