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.
Affected configurations
• arm arm compiler for embedded (>= 6.6 < 6.23)
• arm arm compiler for embedded fusa 6.16
• arm arm compiler for embedded fusa 6.21
• arm arm compiler for functional safety 6.6
• arm clang (>= 11.0.0 < 20.1.0)
