CVE-2024-21460
📋 TL;DR
This vulnerability in Qualcomm chipsets allows information disclosure when Address Space Layout Randomization (ASLR) fails to properly randomize memory regions for IMEM and Secure DDR, treating them as a single chunk. Attackers can potentially bypass ASLR protections to leak sensitive data. This affects devices using vulnerable Qualcomm hardware components.

⚠️ Risk & Real-World Impact
Worst Case
Complete ASLR bypass enabling reliable exploitation of other vulnerabilities, potentially leading to full device compromise and sensitive data exfiltration.
Likely Case
Information disclosure allowing attackers to bypass ASLR and gain memory layout knowledge to facilitate exploitation of other vulnerabilities.
If Mitigated
Limited information leakage with minimal practical impact if proper memory isolation and additional security controls are implemented.
🎯 Exploit Status
Exploitation requires local access or ability to execute code on target device; no public exploit code available.
