Overview
CVE-2025-58478 is a medium-severity vulnerability affecting Samsung devices due to an out-of-bounds write in the libimagecodec.quram.so library. This vulnerability allows remote attackers to potentially access memory outside of the intended bounds, leading to unpredictable behavior and potential security breaches. The issue is addressed in the SMR Dec-2025 Release 1.
Technical Details
The vulnerability resides in the libimagecodec.quram.so library, which is responsible for handling image decoding operations on Samsung devices. An attacker can trigger an out-of-bounds write by providing a specially crafted image file that exploits a flaw in the library’s memory management or bounds checking. Successful exploitation allows the attacker to write data to arbitrary memory locations, potentially corrupting data structures, hijacking control flow, or gaining unauthorized access to sensitive information. The specific flaw lies within how the library processes certain image formats, likely related to size calculations or buffer handling when processing the “quram” format.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-58478 is 4.3, indicating a MEDIUM severity. This score is based on the following factors:
- Attack Vector (AV): Network (N)
- Attack Complexity (AC): Low (L)
- Privileges Required (PR): None (N)
- User Interaction (UI): Required (R)
- Scope (S): Unchanged (U)
- Confidentiality Impact (C): None (N)
- Integrity Impact (I): Low (L)
- Availability Impact (A): None (N)
This score reflects the fact that the vulnerability can be exploited remotely with relative ease, but requires user interaction (e.g., opening a malicious image file). The impact on confidentiality and availability are considered to be low.
Possible Impact
Successful exploitation of CVE-2025-58478 could lead to a variety of negative consequences, including:
- Application Crash: The out-of-bounds write could corrupt critical data structures, causing the application using
libimagecodec.quram.soto crash. - Data Corruption: The vulnerability could be used to overwrite data, potentially leading to data loss or system instability.
- Limited Information Disclosure: While rated as having “None” for confidentiality impact by CVSS, the possibility exists that targeted exploitation could be used to leak small amounts of information depending on memory layout and attacker skill.
- Denial of Service: Repeated exploitation could lead to resource exhaustion or system instability, resulting in a denial-of-service condition.
Mitigation or Patch Steps
The primary mitigation for CVE-2025-58478 is to update your Samsung device to the SMR Dec-2025 Release 1 or later. This update includes a patch that addresses the out-of-bounds write vulnerability in libimagecodec.quram.so. Users should ensure their devices are configured to automatically install security updates to minimize the risk of exploitation.
Specifically, follow these steps:
- Navigate to your device’s settings.
- Find the “Software update” or “System update” section.
- Check for available updates.
- Download and install the SMR Dec-2025 Release 1 update (or any later update).
- Restart your device after the update is installed.
