What is CVE-2024-53104?

CVE-2024-53104 is a vulnerability identified within the Linux kernel’s UVC (USB Video Class) subsystem. This vulnerability arises from improper handling of specific video frame types during parsing operations, which can lead to out-of-bounds write conditions. Such an issue poses a significant risk to organizations relying on affected kernels, as it can allow attackers to execute arbitrary code, potentially leading to system compromise. With widespread usage of Linux in various applications, including servers, desktops, and embedded systems, this vulnerability can impact numerous entities that depend on Linux-based environments for their operations.

Technical Details

The vulnerability occurs in the function responsible for parsing video frames within the uvcvideo driver. Specifically, the UVC_VS_UNDEFINED frame type was not appropriately considered when calculating the size of the frames buffer in the uvc_parse_streaming function. This oversight can allow an attacker to write data outside the allocated memory bounds, leading to potential memory corruption and instability in the kernel. The Linux kernel team has acknowledged this flaw and has provided fixes in subsequent updates to mitigate the risk associated with this vulnerability.

Potential impact of CVE-2024-53104

Arbitrary Code Execution: The primary risk associated with this vulnerability is the potential for arbitrary code execution. An attacker who successfully exploits this flaw could take control of the affected system, leading to unauthorized access to sensitive data and further exploitation.
System Instability and Crashes: Since the vulnerability can cause out-of-bounds writes, it may lead to system instability. This could result in random crashes, data corruption, or denial of service, disrupting organizational operations.
Increased Attack Surface: The presence of this vulnerability in widely used Linux kernel versions opens a larger attack surface for malicious actors. As organizations increasingly rely on Linux-based systems, the exploitation of this vulnerability can facilitate further attacks, including those orchestrated by ransomware groups targeting vulnerable systems.

CISA Reported

CISA provides regional cyber and physical services to support security and resilience across the United States. CISA monitor the most dangerious vulnerabilities and have identifed as being exploited but is not known by the CISA to be used in ransomware campaigns. This is subject to change at pace

The CISA's recommendation is: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
