CVE-2024-7883 describes a vulnerability in Arm Cortex-M Security Extensions (CMSE) when used with LLVM-based compilers. It allows secure stack contents to be leaked to the non-secure state via floating-point registers under specific conditions during a secure-to-non-secure function call returning a floating-point value. This vulnerability affects Arm Compiler for Embedded, Arm Compiler for Embedded FuSa, Arm Compiler for Functional Safety, and Arm Clang. The vulnerability has a CVSS score of 3.7 (LOW), indicating a low impact on confidentiality with high attack complexity and no user interaction required. An attacker could read a limited quantity of secure stack contents. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
