Severity CVSS v4.0:
Pending analysis
Type:
CWE-226 Sensitive Information in Resource Not Removed Before Reuse

Description

When using Arm Cortex-M Security Extensions (CMSE), Secure stack <br /> contents can be leaked to Non-secure state via floating-point registers <br /> when a Secure to Non-secure function call is made that returns a <br /> floating-point value and when this is the first use of floating-point <br /> since entering Secure state. This allows an attacker to read a limited <br /> quantity of Secure stack contents with an impact on confidentiality. <br /> This issue is specific to code generated using LLVM-based compilers.
