An unvalidated input in Silicon Labs TrustZone implementation in v4.3.x and earlier of the Gecko SDK allows an attacker to access the trusted region of memory from the untrusted region.
AnalysisAI
An unvalidated input in Silicon Labs TrustZone implementation in v4.3.x and earlier of the Gecko SDK allows an attacker to access the trusted region of memory from the untrusted region. Rated critical severity (CVSS 9.3), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. An unvalidated input in Silicon Labs TrustZone implementation in v4.3.x and earlier of the Gecko SDK allows an attacker to access the trusted region of memory from the untrusted region. Affected products include: Silabs Gecko Software Development Kit.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.
