Process crash via undersized SLIP CRC frame
Published Jan 21, 2026 · Updated Jan 21, 2026
Out-of-bounds read in the EVerest Core DZG_GSH01 SLIP parser before 2025.12.0 allows physically proximate attackers to crash the process. The multi-message path passes a one-byte sub-message to is_message_crc_correct, which reads two CRC bytes without first validating the vector length. Exploitation requires control of the powermeter serial input and interrupts the affected driver process without reported data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
