NVD Description
Note: Versions mentioned in the description apply only to the upstream llvm-toolchain-15 package and not the llvm-toolchain-15 package as distributed by Debian.
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.
