CVE-2024-2502

Failure to update the tamper reset cause register when a tamper event occurs

Published Aug 29, 2024 CVSS 3.1 · 2 Low EPSS < 1% KEV · Not listed
Description
An application can be configured to block boot attempts after consecutive tamper resets are detected, which may not occur as expected.

This is possible because the TAMPERRSTCAUSE register may not be properly updated when a level 4 tamper event (a tamper reset) occurs. This impacts Series 2 HSE-SVH devices, including xG23B, xG24B, xG25B, and xG28B, but does not impact xG21B. To mitigate this issue, upgrade to SE Firmware version 2.2.6 or later.
