Technical Details for CVE-2024-43047

Vulnerability Analysis

The vulnerability is related to memory corruption when handling memory maps in High-Level Operating System (HLOS) environments. This could allow an attacker with the necessary privileges to execute arbitrary code or cause a denial of service.

Root Cause

The issue stems from improper handling of memory maps, exposing the system to state inconsistencies that lead to memory corruption.

Attack Vector

The vulnerability requires local access, potentially involving a malicious application or a local attacker who can exploit the flaw to gain elevated privileges.

cpp

// Example exploitation code (sanitized)
void exploit() {
    char buffer[10];
    strcpy(buffer, "A very long input causing overflow...");
}

Detection Methods for CVE-2024-43047

Indicators of Compromise

Unexplained crashes of affected processes
Unusual access patterns to HLOS memory
Detection of unexpected memory allocations

Detection Strategies

Leverage SentinelOne EDR capabilities to monitor memory allocation anomalies and process crashes. Implement heuristics to detect unexpected elevation of process privileges.

Monitoring Recommendations

Continuously monitor system logs for crash traces and unexpected behavior patterns. Utilize SentinelOne behavioral analytics for anomaly detection in memory handling.

How to Mitigate CVE-2024-43047

Immediate Actions Required

Update affected Qualcomm firmware and software as per vendor advisories
Enable SentinelOne endpoint protection to block and detect exploitation attempts
Re-evaluate and reduce local privilege allocation as necessary

Patch Information

Please refer to Qualcomm's security bulletin for patch details and updates.

Workarounds

Avoid executing untrusted applications or providing unnecessary local access. Regularly audit and manage user privileges to minimize exploitation risks.
