CVE-2024-53104 Linux Kernel Out-of-Bounds Write

CVE-2024-53104 is a high-severity vulnerability identified in the Linux kernel’s USB Video Class (UVC) driver. This flaw arises from improper parsing of frames labeled as UVC_VS_UNDEFINED within the uvc_parse_format function. The oversight leads to miscalculations in the frame buffer size during the uvc_parse_streaming process, resulting in potential out-of-bounds write operations. Such operations can corrupt memory, potentially allowing attackers to execute arbitrary code or cause system crashes.

What is Vulnerable to CVE-2024-53104

This vulnerability affects multiple versions of the Linux kernel, specifically:

• Versions from 2.6.26 up to, but not including, 4.19.324
• Versions from 4.20 up to, but not including, 5.4.286
• Versions from 5.5 up to, but not including, 5.10.230
• Versions from 5.11 up to, but not including, 5.15.172
• Versions from 5.16 up to, but not including, 6.1.55
• Versions from 6.2 up to, but not including, 6.5.10
• Versions from 6.6 up to, but not including, 6.6.3

Systems running these kernel versions are susceptible to potential exploitation if the UVC driver is active. Notably, Android devices utilizing these kernel versions are also vulnerable.

Mitigation and Remediation for CVE-2024-53104

To address this vulnerability, the following steps are recommended:

1. Kernel Update: Update to the latest Linux kernel version where the vulnerability has been patched. The issue has been resolved in the following versions:

   • 4.19.324
   • 5.4.286
   • 5.10.230
   • 5.15.172
   • 6.1.55
   • 6.5.10
   • 6.6.3

   Ensure that your system is updated to one of these versions or later.

3. System Monitoring: Continuously monitor systems for any unusual activity that could indicate exploitation attempts.

Impact of Successful Exploitation of CVE-2024-53104

If successfully exploited, this vulnerability can lead to:

• Privilege Escalation: Attackers can gain elevated privileges, potentially granting them unauthorized access to sensitive system areas.
• Arbitrary Code Execution: Malicious actors may execute arbitrary code, leading to unauthorized actions within the system.
• Denial of Service (DoS): Exploitation can cause system crashes or instability, resulting in service disruptions.

Given the active exploitation of this vulnerability in targeted attacks, as noted by Google, immediate remediation is essential.

Proof of Concept for CVE-2024-53104

As of now, there is no publicly available proof-of-concept (PoC) exploit for CVE-2024-53104. However, given the nature of the vulnerability, exploitation would likely involve crafting malicious USB video data that, when processed by the vulnerable UVC driver, triggers the out-of-bounds write. Security researchers and organizations are advised to monitor official channels and security forums for any updates or shared PoC code.

In conclusion, CVE-2024-53104 represents a significant security risk due to its potential for severe exploitation and the fact that it has been observed in active, targeted attacks. Prompt action to update affected systems and apply necessary patches is crucial to safeguard against potential threats.
