CVE-2024-53104 is a high-severity vulnerability affecting Debian Linux and the Linux kernel. This vulnerability allows out-of-bounds writes due to improper handling of certain frame types in the USB Video Class (UVC) driver. The vulnerability arises within the uvc_parse_streaming function, where frames of type UVC_VS_UNDEFINED are not accounted for during buffer size calculations, leading to potential data corruption and system instability.
With a CVSS score of 7.8, this vulnerability is classified as high severity, indicating a significant risk to organizations utilizing affected systems. Attackers may leverage this vulnerability locally, which means that only authenticated users or applications can exploit it, but the potential for damage could be substantial.
The urgency for defenders is critical, as the vulnerability is included in the Known Exploited Vulnerabilities (KEV) catalog. Organizations should prioritize patching immediately to mitigate the risk of exploitation.
Failure to address this vulnerability could lead to unauthorized access and potential compromise of sensitive data. It is crucial for organizations to stay informed about this threat and take appropriate actions.
Vulnerability Details
The official CVE description states that the vulnerability is found in the Linux kernel. The issue pertains to the media subsystem, specifically in the uvcvideo driver, where frames of type UVC_VS_UNDEFINED were not correctly parsed. This oversight can lead to out-of-bounds writes, posing a significant risk to system integrity.
The vulnerability is identified as CWE-787, which refers to 'Out-of-bounds Write'. The CVSS score of 7.8 indicates that the vulnerability has high confidentiality, integrity, and availability impacts.
Affected products include Debian Linux and the Linux kernel across various versions. The vulnerability was published on December 2, 2024.
Technical Analysis
The root cause of CVE-2024-53104 stems from insufficient validation of frame types in the uvc_parse_format function, allowing certain frames to be ignored during size calculations. This can lead to buffer overflows and subsequent out-of-bounds writes.
The attack vector for this vulnerability is local, as it requires authenticated access to the system. The attack complexity is low, with minimal privileges required for exploitation. User interaction is not required, making this vulnerability particularly concerning.
The impacts of exploitation include high confidentiality, integrity, and availability impacts, leading to potential system crashes or data corruption.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access and the compromise of sensitive data. Given the high severity rating, the vulnerability poses a significant threat, especially within environments where the Linux kernel is widely deployed.
The blast radius for this vulnerability could extend to all systems running affected versions of the Debian Linux and Linux kernel, amplifying the urgency for remediation. Organizations should assess their exposure and take immediate action.
Organizations should address this vulnerability in their priority patch cycle, as the potential for exploitation is critical. The inclusion of this vulnerability in the KEV catalog signals its active exploitation risk, necessitating prompt attention.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | Yes |
Ransomware Use | No |
Affected Versions
Affected versions include Debian Linux 11.0 and various versions of the Linux kernel, specifically those prior to vendor patches that address this vulnerability. Organizations should evaluate their systems to determine if they are running any vulnerable versions.
Mitigation & Remediation
To mitigate this vulnerability, organizations should apply the latest patches provided by the Debian and Linux vendors. Immediate action is required to upgrade to the latest version that resolves this issue.
In cases where an immediate patch is not available, organizations should consider implementing configuration hardening and network controls to limit exposure. Additionally, continuous monitoring of systems for any unauthorized access attempts is recommended.
Penetration testing can also be utilized to validate the effectiveness of remediation efforts.
Detection Guidance
Organizations should monitor logs for indicators of unauthorized access or anomalous behavior associated with this vulnerability. Behavioral anomalies in the uvcvideo driver should be scrutinized, particularly in environments where the Linux kernel is deployed.
In addition, network signatures associated with the exploitation of this vulnerability should be established to help detect potential attacks.
