CVE-2014-3180

What is this vulnerability?

CVE-2014-3180 is categorized as a critical Out-of-bounds Read flaw with a CVSS base score of 9.1. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.

In kernel/compat.c in the Linux kernel before 3.17, as used in Google Chrome OS and other products, there is a possible out-of-bounds read. restart_syscall uses uninitialized data when restarting compat_sys_nanosleep. NOTE: this is disputed because the code path is unreachable

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-2014-3180

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.

Defending with Precogs AI

The Linux kernel's compat subsystem (used in older Android/ChromeOS versions) contains a vulnerability allowing local privilege escalation. Attackers execute a crafted application that exploits memory corruption in 32-bit to 64-bit translation layers to gain root access. Precogs Binary SAST uncovers missing bounds checks in system call interfaces.

Vulnerability Code Signature

Attack Data Flow

Vulnerable Code Pattern

// ❌ VULNERABLE: Out-of-bounds read
void read_data(char *input, int length) {
    char buffer[64] = {0};
    // Taint sink: reads beyond buffer size if length > 64
    memcpy(buffer, input, length);
}

Secure Code Pattern

// ✅ SECURE: Bounded read
void read_data(char *input, int length) {
    char buffer[64] = {0};
    // Sanitized boundary check
    int safe_length = (length > sizeof(buffer)) ? sizeof(buffer) : length;
    memcpy(buffer, input, safe_length);
}
