CVE-2024-33070
📋 TL;DR
This vulnerability allows an attacker to cause a denial-of-service (DoS) condition by sending specially crafted beacon or probe response frames containing malformed ESP IE (Extended Service Period Information Element) data. It affects systems using Qualcomm Wi-Fi chipsets that process these wireless frames. The attack requires proximity to the target device within Wi-Fi range.
💻 Affected Systems
- Qualcomm Wi-Fi chipsets and devices using them
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Permanent device crash requiring physical restart, disrupting critical wireless communications in environments like healthcare, industrial control, or emergency services.
Likely Case
Temporary service disruption where affected devices reboot or disconnect from Wi-Fi networks, causing intermittent connectivity issues.
If Mitigated
Minimal impact with proper network segmentation and monitoring; affected devices automatically recover after brief disruption.
🎯 Exploit Status
Exploitation requires crafting and transmitting malicious wireless frames, which can be done with standard wireless penetration testing tools. No authentication needed as beacon/probe responses are broadcast/multicast frames.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Firmware updates specified in Qualcomm October 2024 security bulletin
