CVE-2024-53104: Linux Kernel UVC Buffer Overflow Flaw

CVE-2024-53104 Overview

In the Linux kernel, the following vulnerability has been resolved:

media: uvcvideo: Skip parsing frames of type UVC_VS_UNDEFINED in uvc_parse_format. This can lead to out-of-bounds writes since frames of this type were not taken into account when calculating the size of the frames buffer in uvc_parse_streaming.

Critical Impact
The ability to trigger out-of-bounds writes could allow attackers to execute arbitrary code or cause a denial of service, impacting the integrity and availability of the system.

Affected Products

Debian Debian Linux
Linux Kernel

Technical Details for CVE-2024-53104

Vulnerability Analysis

The vulnerability arises from improper handling of certain frame types (UVC_VS_UNDEFINED) in the uvc_parse_format function. This oversight can lead to buffer miscalculations and potential memory corruption, specifically out-of-bounds writes.

Root Cause

The root cause of this issue is a failure to properly account for certain frame types during size calculations of the frame buffer in uvc_parse_streaming.

Attack Vector

The attack vector is local, requiring an attacker to have the ability to execute code on the vulnerable system.

// Example exploitation code (sanitized)
void exploit_function() {
    char buffer[64];
    // Simulate out-of-bounds write
    strcpy(buffer, "Long string that exceeds buffer length...");
}

Detection Methods for CVE-2024-53104

Indicators of Compromise

Unusual system crashes or memory access errors
Unexpected behaviors in applications using video functionalities

Detection Strategies

Implement host-based intrusion detection systems to monitor for abnormal process behaviors and memory access patterns.

Monitoring Recommendations

Enable detailed logging for kernel processes and monitor for anomalies related to buffer overflow attempts.

How to Mitigate CVE-2024-53104

Immediate Actions Required

Upgrade to the latest patched version of the Linux kernel.
Review system and application permissions to minimize local attack opportunities.
Monitor for vendor updates and advisories.

Patch Information

Patches have been released by the Linux maintainers and can be accessed here.

Workarounds

Currently, the application of the official patch is the most reliable fix. Consider implementing additional security controls such as mandatory access controls (MAC) to restrict unauthorized interactions with the uvcvideo module.

bash

# Example workaround configuration
setenforce 1   # Enforce SELinux policies to limit exploitability
