CVE-2024-55569 is a high-severity vulnerability affecting a broad range of Samsung processors, including Mobile Processors, Wearable Processors, and various Exynos modem models such as the 980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 9110, W920, W930, W1000, and Modem variants 5123, 5300, and 5400. The core issue is a lack of proper length checking in the affected components, which leads to out-of-bounds (OOB) writes. This type of vulnerability is classified under CWE-787, indicating a buffer overflow or memory corruption flaw. The absence of length validation means that an attacker could potentially write data beyond the intended buffer boundaries, corrupting adjacent memory regions. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), the vulnerability is remotely exploitable over the network without any privileges or user interaction, and it impacts availability only, not confidentiality or integrity. This suggests that exploitation could cause denial of service (DoS) conditions, such as device crashes or reboots, by corrupting critical memory areas. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability affects a wide range of Samsung’s Exynos processors used in mobile phones, wearables, and modems, which are integral to device operation and communication. The broad product coverage increases the attack surface significantly. Given the nature of the vulnerability, attackers could disrupt device functionality remotely, potentially impacting user experience and service availability.

For European organizations, the impact of CVE-2024-55569 could be significant, especially for those relying on Samsung-based mobile devices, IoT wearables, or embedded systems using the affected Exynos processors. The vulnerability’s ability to cause out-of-bounds writes leading to availability disruption could result in device crashes or network outages. This is particularly critical for sectors that depend on continuous mobile connectivity and wearable health or industrial monitoring devices, such as healthcare providers, manufacturing, logistics, and telecommunications. Disruptions could lead to operational downtime, loss of productivity, and potential safety risks if critical monitoring devices fail. Additionally, mobile workforce operations relying on Samsung devices could face interruptions. Although the vulnerability does not directly compromise confidentiality or integrity, the denial of service impact can indirectly affect business continuity and service reliability. The lack of required privileges or user interaction for exploitation increases the risk profile, as attackers could remotely trigger the vulnerability without user awareness.

1. Immediate monitoring of vendor advisories and Samsung security bulletins is essential to obtain official patches or firmware updates addressing this vulnerability. 2. Organizations should inventory all Samsung devices and embedded systems using the affected Exynos processors to assess exposure. 3. Network-level protections such as firewall rules and intrusion detection systems should be tuned to detect and block anomalous traffic patterns targeting these devices, especially from untrusted networks. 4. Employ network segmentation to isolate critical devices and reduce the attack surface. 5. For wearable and IoT devices, ensure secure update mechanisms are in place to facilitate rapid deployment of patches once available. 6. Engage with device manufacturers and service providers to confirm patch availability and deployment timelines. 7. Implement robust device monitoring to detect abnormal reboots or crashes that may indicate exploitation attempts. 8. Consider temporary operational mitigations such as disabling vulnerable features or limiting device exposure to external networks until patches are applied. 9. Educate IT and security teams about the vulnerability’s characteristics to improve incident response readiness.
