In the Linux kernel, the following vulnerability has been resolved: media: atomisp: prevent integer overflow in sh_css_set_black_frame(). The "height" and "width" values come from the user so the "height * width" multiplication can overflow.
This vulnerability allows for local exploitation due to the integer overflow, which could result in high availability impact. The CVSS score for this vulnerability is 5.5, indicating a medium severity level that organizations should not overlook.
Risk to organizations includes potential service disruptions caused by the overflow. Attackers may leverage this vulnerability to crash services or applications relying on the affected kernel code.
Organizations should prioritize patching immediately. As of now, there are no known exploits or public proof of concepts associated with this vulnerability, which provides a window for remediation.
Vulnerability Details
The vulnerability identified as CVE-2022-50399 has been classified under CWE-190 (Integer Overflow or Wraparound). This vulnerability affects the Linux kernel, specifically the media processing component responsible for handling black frame settings.
With a CVSS version of 3.1, the attack vector is local, requiring low complexity and low privileges. There is no user interaction required, and the availability impact is rated as high, making this a significant concern for systems running vulnerable versions.
The vulnerability was published on September 18, 2025, and has been modified since its initial disclosure. This emphasizes the ongoing need for vigilance and timely updates in the Linux ecosystem.
Technical Analysis
The root cause of this vulnerability is an integer overflow during the multiplication of user-supplied height and width values. Given that these values can be manipulated by an attacker, the multiplication can exceed the maximum allowable value, leading to resource exhaustion or denial of service.
The attack vector is local, meaning the attacker must have access to the system where the kernel is running. The complexity is low, and the required privileges are also low, making it relatively easy for an attacker with minimal access to exploit this vulnerability.
User interaction is not required for exploitation, which further increases the risk. The impact on availability is high, as the overflow can cause system crashes, making it critical to address.
Risk & Impact Analysis
Real-world risk stemming from this vulnerability includes potential downtime or service interruptions in applications relying on the Linux kernel. Given its local exploitability and the low barrier to execution, organizations should consider the blast radius of this vulnerability as significant.
The urgency for organizations to patch this vulnerability is high, considering the CVSS score of 5.5 and the potential for high availability impact. Organizations should assess their use of affected kernel versions and prioritize remediation.
This vulnerability exemplifies a pattern in software vulnerabilities where user input can lead to critical system failures. Proactive patching and system monitoring are essential to mitigate such risks.
