OESA-2026-2072 (CVE-2024-7883)

Vulnerability from osv_openeuler – Published: 2026-04-25 11:11 – Updated: 2026-08-06 11:11 – Source website

Summary

llvm security update

Details

LLVM is a compiler infrastructure designed for compile-time, link-time, runtime, and idle-time optimization of programs from arbitrary programming languages.

Security Fix(es):

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.(CVE-2024-7883)

Severity

3.7 (Low)
