Insufficient Entropy Affecting SiliconLabs/simplicity_sdk package, versions [0,]
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

There is no fixed version for SiliconLabs/simplicity_sdk.
Overview
Affected versions of this package are vulnerable to Insufficient Entropy in the SYMCRYPTO process due to reduced entropy in DPA countermeasures when certain seed values are forced. An attacker can increase the likelihood of cryptographic key extraction by executing code on the affected device. This is only exploitable if the attacker has already achieved code execution capability on the device.
