CVE-2024-7883
Arm Cortex-M Security Extensions (CMSE) Floating-Point Registers Leaky Secure Stack (Vendor/ProductName Secure Stack Confidentiality Leakage)
Description

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