CVE-2024-7883— CMSE secure state may leak from stack to floating-point registers
Quick assessment
Affected
Arm Ltd Arm Compiler for Embedded
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
ARM Compiler是英国ARM公司的一个用于编译生成ARM架构应用的工具。 ARM Compiler 6.6版本至6.22版本存在安全漏洞，该漏洞源于如果执行了安全到非安全函数调用并返回浮点值，并且这是进入安全状态以来首次使用浮点，则安全堆栈内容可能会通过浮点寄存器泄露到非安全状态，这允许攻击者读取有限数量的安全堆栈内容，从而影响机密性。

Vulnerability Title
CMSE secure state may leak from stack to floating-point registers
Source: CVE Program / CVE List V5
Vulnerability 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.
