CVE-2013-2597: n/a in n/a
Stack-based buffer overflow in the acdb_ioctl function in audio_acdb.c in the acdb audio driver for the Linux kernel 2.6.x and 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to gain privileges via an application that leverages /dev/msm_acdb access and provides a large size value in an ioctl argument.
AI Analysis
Technical Summary
CVE-2013-2597 is a high-severity stack-based buffer overflow vulnerability located in the acdb_ioctl function within the audio_acdb.c source file of the acdb audio driver. This driver is part of the Linux kernel versions 2.6.x and 3.x, specifically in Qualcomm Innovation Center (QuIC) Android contributions targeting MSM (Mobile Station Modem) devices and other related products. The vulnerability arises when an attacker-controlled application accesses the device node /dev/msm_acdb and issues an ioctl system call with a crafted argument containing an excessively large size value. This malformed input causes the acdb_ioctl function to overflow a stack buffer, potentially allowing the attacker to overwrite critical control data on the stack. Exploitation of this vulnerability can lead to privilege escalation, enabling an unprivileged application to gain kernel-level privileges without requiring user interaction or prior authentication. The vulnerability is classified under CWE-121 (Stack-based Buffer Overflow), which is a common and dangerous class of memory corruption bugs. The CVSS 3.1 base score is 8.4 (high), reflecting the vulnerability's ability to compromise confidentiality, integrity, and availability with relatively low attack complexity and no need for privileges or user interaction. Although no public exploits are currently known in the wild, the vulnerability affects foundational components of the Linux kernel used in many Android devices based on Qualcomm MSM chipsets, making it a significant risk vector for embedded and mobile systems relying on these kernels.
Potential Impact
For European organizations, the impact of CVE-2013-2597 is primarily relevant to entities using Android devices or embedded systems powered by Qualcomm MSM chipsets running vulnerable Linux kernel versions 2.6.x or 3.x. Successful exploitation can lead to full system compromise on affected devices, enabling attackers to bypass security controls, access sensitive data, install persistent malware, or disrupt device functionality. This is particularly concerning for sectors such as telecommunications, critical infrastructure, government agencies, and enterprises with Bring Your Own Device (BYOD) policies, where compromised mobile endpoints can serve as entry points into corporate networks. Additionally, embedded systems in industrial control, automotive, or IoT devices using these kernels could be at risk, potentially impacting operational technology environments. The vulnerability's ability to escalate privileges without user interaction increases the risk of stealthy attacks and lateral movement within networks. Although the vulnerability dates back to older kernel versions, many legacy or specialized devices in European organizations may still be running these versions, especially in industrial or embedded contexts, thus maintaining exposure.
Mitigation Recommendations
1. Patch Management: Although no direct patch links are provided, organizations should ensure all affected devices are updated to Linux kernel versions beyond 3.x where this vulnerability is resolved. For Android devices, applying official security updates from device manufacturers or Qualcomm is critical. 2. Device Inventory and Assessment: Identify and inventory all devices running vulnerable kernel versions, especially those with Qualcomm MSM chipsets, to prioritize remediation efforts. 3. Access Control: Restrict access to the /dev/msm_acdb device node to trusted system components only, using strict file permissions and SELinux/AppArmor policies to prevent unprivileged applications from invoking ioctl calls. 4. Application Whitelisting: Implement application control policies to prevent untrusted or potentially malicious applications from executing on devices, reducing the risk of exploitation. 5. Network Segmentation: Isolate vulnerable devices from critical network segments to limit potential lateral movement if compromise occurs. 6. Monitoring and Detection: Deploy host-based intrusion detection systems (HIDS) and monitor for anomalous ioctl calls or privilege escalation attempts on devices. 7. Vendor Coordination: Engage with device and chipset vendors to obtain security advisories and patches, especially for embedded and industrial devices that may not receive regular updates.
