CVE-2025-58480 is a heap-based buffer overflow vulnerability identified in the libimagecodec.quram.so library used by Samsung Mobile devices. This vulnerability arises from improper bounds checking when processing image data, allowing remote attackers to trigger out-of-bounds memory access. The flaw exists in versions prior to the Samsung Mobile Security Maintenance Release (SMR) December 2025 Release 1. Exploitation requires no privileges (AV:N/PR:N) but does require user interaction (UI:R), such as opening or previewing a maliciously crafted image file. The vulnerability impacts the integrity of the device by potentially corrupting memory, which could be leveraged to alter program behavior or execute arbitrary code, although no direct confidentiality or availability impacts are indicated. The CVSS 3.1 base score is 4.3, reflecting medium severity due to the need for user interaction and the limited scope of impact. No known exploits have been reported in the wild, and no official patches have been linked yet, though Samsung is expected to address this in their December 2025 security update. The vulnerability is categorized under CWE-122, a common weakness related to heap-based buffer overflows, which are often exploited to execute arbitrary code or cause denial of service. Given the ubiquity of Samsung Mobile devices worldwide, this vulnerability presents a significant risk if exploited, especially in environments where users may open untrusted image content.

For European organizations, this vulnerability poses a moderate risk primarily to the integrity of Samsung Mobile devices used within corporate environments or by employees. Successful exploitation could allow attackers to manipulate device behavior or potentially execute arbitrary code, which could be leveraged for further lateral movement or data manipulation. Although confidentiality and availability impacts are not directly indicated, compromised device integrity can undermine trust in mobile communications and applications, potentially affecting sensitive business operations. The requirement for user interaction limits mass exploitation but targeted phishing or social engineering campaigns could increase risk. Organizations relying heavily on Samsung Mobile devices for secure communications, mobile workforce operations, or sensitive data access should be particularly vigilant. The widespread adoption of Samsung smartphones in Europe means that many enterprises and government entities could be affected, increasing the potential attack surface. Additionally, the lack of currently available patches means organizations must rely on interim mitigations until the official update is released.

1. Monitor Samsung’s official security advisories and promptly apply the SMR December 2025 Release 1 update once it becomes available to ensure the vulnerability is patched. 2. Implement mobile device management (MDM) solutions to enforce update policies and restrict installation of untrusted applications or media. 3. Educate users about the risks of opening unsolicited or suspicious image files, especially from unknown sources, to reduce the likelihood of user interaction-based exploitation. 4. Employ network-level protections such as filtering or sandboxing of image content received via email or messaging platforms to detect and block malicious payloads. 5. Conduct regular security awareness training focused on social engineering tactics that could lead to exploitation of this vulnerability. 6. For high-risk environments, consider restricting the use of Samsung Mobile devices or isolating them within segmented network zones until patches are applied. 7. Utilize endpoint detection and response (EDR) tools capable of monitoring anomalous behavior on mobile devices that could indicate exploitation attempts.
