CVE-2015-9073

What is this vulnerability?

CVE-2015-9073 is categorized as a critical NULL Pointer Dereference flaw with a CVSS base score of 9.8. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.

In all Qualcomm products with Android releases from CAF using the Linux kernel, an untrusted pointer dereference can occur in a TrustZone syscall.

This architectural defect enables adversaries to bypass intended security controls, directly manipulating the application's execution state or data layer. Immediate strategic intervention is required.

Risk Assessment

Impact on Systems

✅ Remote Code Execution: Attackers can overwrite the instruction pointer to redirect execution to malicious shellcode.

✅ Memory Corruption: Overwriting adjacent memory regions can corrupt critical application state, leading to privilege escalation.

✅ Denial of Service: Triggering segmentation faults results in immediate disruption of critical systems.

How to Fix and Mitigate CVE-2015-9073

1. Apply Vendor Patches: Upgrade affected components to their latest, non-vulnerable versions immediately.
2. Implement Input Validation: Ensure all user-supplied data is validated, sanitized, and type-checked before processing.
3. Deploy Runtime Protection: Use Precogs continuous monitoring to detect exploitation attempts in real time.
4. Audit Dependencies: Review and update all third-party libraries and transitive dependencies.

Vulnerability Code Signature

Attack Data Flow

Vulnerable Code Pattern

// ❌ VULNERABLE: NULL Pointer Dereference
void process_data() {
    char *buffer = malloc(1024);
    // Taint sink: accessing pointer without NULL check
    buffer[0] = 'A';
}

Secure Code Pattern

// ✅ SECURE: NULL check
void process_data() {
    char *buffer = malloc(1024);
    // Sanitized validation
    if (buffer != NULL) {
        buffer[0] = 'A';
    }
}
