CVE-2024-47026
📋 TL;DR
This vulnerability allows an attacker to read memory beyond intended boundaries in the gsc_gsa_rescue function of gsc_gsa.c, potentially exposing sensitive information stored in adjacent memory. It affects Android devices, particularly Google Pixel phones, and requires no user interaction or special privileges to exploit.
💻 Affected Systems
- Google Pixel phones
- Android devices with Qualcomm GSC firmware
📦 What is this software?
Android by Google
⚠️ Risk & Real-World Impact
Worst Case
An attacker could read sensitive kernel memory containing cryptographic keys, passwords, or other protected data, leading to complete system compromise.
Likely Case
Local information disclosure where an attacker with physical or remote access could extract limited system information from kernel memory.
If Mitigated
With proper kernel hardening and memory protection mechanisms, exploitation would be limited to reading non-sensitive data or cause system crashes.
🎯 Exploit Status
Exploitation requires understanding of kernel memory layout and driver interaction, but no authentication or user interaction is needed.

adb shell settings put secure install_non_market_apps 0
🧯 If You Can't Patch
- Isolate affected devices from sensitive networks and data
- Implement strict application whitelisting to prevent malicious apps from running
🔍 How to Verify
Check if Vulnerable:
Check Android security patch level in Settings > About phone > Android version. If patch level is before October 2024, device is vulnerable.Check Version:
adb shell getprop ro.build.version.security_patchVerify Fix Applied:
Verify security patch level shows 'October 5, 2024' or later in Settings > About phone > Android version.📡 Detection & Monitoring
