CVE-2024-24857 is a race condition vulnerability found in the Linux kernel's net/bluetooth device driver, specifically in the conn_info_{min,max}_age_set() function. This vulnerability allows for an integrity overflow issue that may result in abnormal Bluetooth connections or a denial of service. The severity level is classified as medium, with a CVSS score of 4.6 indicating its potential impact on systems.
Risk to organizations includes disruptions to Bluetooth connectivity, which can affect operations dependent on Bluetooth technology. Immediate attention is required, as the potential for service interruption poses a significant risk to operational efficiency.
As of now, no known exploits are available, and it is not actively exploited in the wild. However, organizations should prioritize patching to mitigate the risk of future exploitation.
Organizations should prioritize patching immediately.
Vulnerability Details
The official description for CVE-2024-24857 states that a race condition was found in the Linux kernel's net/bluetooth device driver in the conn_info_{min,max}_age_set() function. This vulnerability can lead to an integrity overflow issue, potentially resulting in abnormal Bluetooth connections or denial of service. The vulnerability has a CVSS score of 4.6, indicating a medium severity level.
Affected products include Debian Linux (version 10.0 and potentially other versions of the Linux kernel). The vulnerability is classified under CWE-362 (Race Condition) and CWE-190 (Integer Overflow or Wraparound).
The CVE was published on February 5, 2024, and has been analyzed for its impact and potential exploitation vectors.
Technical Analysis
The root cause of this vulnerability is due to a race condition in the implementation of the Bluetooth device driver. This condition can allow multiple threads to access shared resources without proper synchronization, leading to unexpected behavior, such as integrity overflow.
The attack vector is classified as adjacent network, indicating that an attacker must be within the local network segment to exploit this vulnerability. The complexity of the attack is considered high, as it requires specific conditions to be met. The required privileges to execute an attack are high, necessitating significant access to the system.
User interaction is required for this vulnerability to be exploited, which adds another layer of difficulty for potential attackers. The impact on confidentiality is none, while the integrity impact is high, and availability impact is low.
Risk & Impact Analysis
The real-world risk of this vulnerability centers around its potential to disrupt Bluetooth connectivity, which is critical for many devices and systems. Organizations relying on Bluetooth technology may face operational downtime if this issue is exploited. Given the medium CVSS score and the nature of the vulnerability, it is prudent for organizations to assess their exposure and take necessary actions.
The urgency of addressing this vulnerability should be classified as medium. While there is currently no known active exploitation, the potential for future attacks remains. Organizations should monitor their systems and apply patches as they become available.
