A critical vulnerability (CVE-2024-43047) in Qualcomm’s Digital Signal Processor exposes systems to privilege escalation.
Affected Platform
CVE-2024-43047 affects devices utilizing Qualcomm’s Snapdragon Digital Signal Processor (DSP). Embedded in millions of Android smartphones, Qualcomm’s DSP processors are vital in mobile environments due to their ability to handle complex multimedia tasks and real-time data without compromising battery efficiency. This widespread adoption means that the vulnerability has the potential to affect a vast user base if left unpatched.
Summary
CVE-2024-43047 is a critical zero-day vulnerability in Qualcomm’s DSP service, allowing attackers to execute arbitrary code on affected devices, which can lead to unauthorized access and privilege escalation. The vulnerability has been assigned a CVSS score of 7.8, classifying it as “high” due to its ease of exploitation and potential for significant impact.
This vulnerability is actively being exploited in the wild, as highlighted by recent reports. Attackers are targeting vulnerable Android devices, bypassing built-in security layers to gain control over critical system resources.

Mechanism of the CVE-2024-43047 Threat
The CVE-2024-43047 vulnerability lies within the DSP component of Qualcomm chipsets. DSPs handle a wide array of computational tasks, including signal processing, multimedia encoding, and machine learning computations. The flaw allows attackers to send specially crafted inputs to the DSP, exploiting a flaw in how it manages memory and processes external commands.
The vulnerability is triggered by a buffer overflow scenario within the DSP service. An attacker with knowledge of the system’s architecture can create inputs that overflow the memory buffer, leading to code injection. This can give the attacker control over the DSP, bypassing security features like SELinux and sandboxing, which are designed to isolate apps and processes.
Exploitation Process
Exploitation of CVE-2024-43047 begins with an attacker delivering malicious code to the vulnerable DSP. This is often achieved through either phishing campaigns, malicious apps, or social engineering attacks. Once inside the system, the malicious code interacts with the DSP, initiating the buffer overflow that allows for arbitrary code execution.
Given the architecture of modern Android smartphones, once the DSP is compromised, an attacker can escalate privileges across the device. They can potentially gain access to sensitive user data, initiate system-level changes, or even install persistent malware that operates stealthily in the background.
Several sources have confirmed that attackers are actively targeting high-profile Android users, making this a significant threat not just to individuals but also to enterprises reliant on Android-based corporate devices.
Impact and Potential Risks
CVE-2024-43047 exposes affected devices to a wide range of risks:
- Privilege Escalation: Attackers can gain root-level access, allowing them to control critical system functions and bypass security protocols.
- Data Exfiltration: With elevated privileges, attackers can steal personal data, credentials, and sensitive information.
- Remote Access: Once exploited, attackers can install backdoors to maintain remote access, even after software updates.
- System Instability: Exploiting the DSP could lead to device crashes, battery drainage, and other performance issues.
- Corporate Espionage: In enterprise environments, compromised devices could serve as entry points into larger corporate networks, leading to widespread data breaches.
The criticality of the vulnerability and its active exploitation means that any delay in mitigation could result in significant damage to both personal and enterprise environments.
Mitigation
Mitigating the risk of CVE-2024-43047 requires immediate action. In addition to applying the official patch, device users and administrators should be actively preventing lateral movement and adopting other best practices:
- Limit Third-Party Application Installs: Restrict apps to trusted sources such as Google Play.
- Use Mobile Device Management (MDM): For corporate environments, enforcing strict app usage policies can minimize exposure.
- Monitor Device Behavior: Be alert to unusual device behavior such as overheating, slow performance, or unexpected app crashes.
- Enable Enhanced Security Settings: Enabling features such as Google Play Protect, two-factor authentication, and app permissions auditing can offer additional layers of defense.
- Deploy Network-Level Security Controls: Organizations should consider implementing mobile security measures like DNS filtering and intrusion detection systems. Review your network security strategy regularly to ensure continued implementation of evolving best practices.
Official Patching Information
Qualcomm has released patches for CVE-2024-43047 through its OEM partners, including major Android device manufacturers. As per Qualcomm’s official security bulletin, users should apply these patches as soon as possible to prevent the risk of exploitation.
Corporate IT teams should enforce these patches across all devices within their network. This is especially important for organizations that rely on mobile devices for accessing corporate resources.
For those using affected devices, ensuring that your system is updated to the latest version is critical. Many Android devices may not automatically receive updates, especially those that are no longer supported by their OEM. Users should check with their device manufacturer for patch availability and consider upgrading to a more secure device if no updates are forthcoming.
