CVE-2025-58477 is a vulnerability classified under CWE-787 (Out-of-bounds Write) found in Samsung Mobile devices. The issue resides in the libimagecodec.quram.so library, which is responsible for parsing Image File Directory (IFD) tags within image files. Specifically, the vulnerability allows a remote attacker to craft a malicious image file that, when processed by the vulnerable library, triggers an out-of-bounds write operation. This can corrupt memory adjacent to the intended buffer, potentially leading to integrity violations such as data corruption or unexpected behavior within the affected process. The vulnerability does not directly compromise confidentiality or availability, but the integrity impact could be leveraged in complex attack chains. The CVSS 3.1 base score is 4.3 (medium), with vector AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N, indicating network attack vector, low attack complexity, no privileges required, but user interaction is necessary (e.g., opening a malicious image). The scope is unchanged, meaning the impact is confined to the vulnerable component. No patches were available at the time of publication, but the issue is addressed in the Samsung Mobile Security Maintenance Release (SMR) December 2025 update. No known exploits have been reported in the wild, suggesting limited active exploitation currently. The vulnerability affects all Samsung Mobile devices using the vulnerable library version prior to the SMR Dec-2025 Release 1. Attackers could exploit this flaw by delivering malicious images via email, messaging apps, or web content, relying on user action to trigger the vulnerability.

For European organizations, the primary impact of CVE-2025-58477 lies in the potential compromise of data integrity on Samsung mobile devices. While it does not directly lead to data leakage or denial of service, the out-of-bounds write could be used as a foothold in multi-stage attacks, potentially enabling privilege escalation or code execution in combination with other vulnerabilities. Organizations relying heavily on Samsung mobile devices for communication, especially in sectors like finance, government, and critical infrastructure, may face increased risk if attackers craft targeted malicious content to exploit this flaw. The requirement for user interaction reduces the likelihood of widespread automated exploitation but does not eliminate targeted spear-phishing or social engineering risks. The absence of known exploits in the wild currently limits immediate impact, but the vulnerability's presence in widely used devices means that unpatched systems remain at risk. Additionally, mobile device management and security policies may need to be reviewed to mitigate potential exploitation vectors.

To mitigate CVE-2025-58477 effectively, European organizations should prioritize the following actions: 1) Deploy the Samsung Mobile Security Maintenance Release (SMR) December 2025 update as soon as it becomes available to patch the vulnerable libimagecodec.quram.so library. 2) Implement strict controls on the handling of image files from untrusted sources, including disabling automatic image previews in messaging and email clients where feasible. 3) Educate users about the risks of opening unsolicited or suspicious image attachments, emphasizing cautious behavior to reduce user interaction exploitation. 4) Utilize mobile endpoint protection platforms capable of detecting anomalous behavior related to memory corruption or exploitation attempts on Samsung devices. 5) Enforce application whitelisting and sandboxing to limit the impact of potential exploitation within the mobile environment. 6) Monitor network traffic and device logs for unusual activity indicative of exploitation attempts. 7) Coordinate with Samsung support and security advisories to stay informed about patch releases and emerging threats related to this vulnerability.
