CVE-2024-32631
📋 TL;DR
CVE-2024-32631 is an out-of-bounds read vulnerability in the ciCCIOTOPT component of ASR180X chipsets that can cause incorrect computations. This affects devices using ASR180X chipsets, potentially allowing attackers to read sensitive memory or cause system instability. The vulnerability primarily impacts embedded systems and IoT devices utilizing these specific chipsets.
💻 Affected Systems
- ASR180X chipsets
- Devices using ASR180X chipsets
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Information disclosure of sensitive memory contents, system crashes leading to denial of service, or potential remote code execution through memory corruption chaining.
Likely Case
System instability, crashes, or information leakage from adjacent memory regions, potentially exposing sensitive data or causing service disruption.
If Mitigated
Limited impact with proper memory protection mechanisms and segmentation, potentially only causing localized crashes in affected components.
🎯 Exploit Status
Exploitation requires specific conditions to trigger the out-of-bounds read, and weaponization status is not publicly confirmed.
