Overview
CVE-2025-58477 is a security vulnerability affecting Samsung devices. It involves an out-of-bounds write error in the libimagecodec.quram.so library, specifically during the parsing of IFD (Image File Directory) tags. This vulnerability, if exploited, could allow remote attackers to potentially access memory outside of allocated buffers, leading to code execution or denial of service.
The vulnerability affects devices with versions of libimagecodec.quram.so prior to the SMR (Security Maintenance Release) of December 2025 Release 1.
Technical Details
The vulnerability stems from improper bounds checking within the libimagecodec.quram.so library when processing IFD tags within image files. An attacker could craft a malicious image file containing a specifically designed IFD tag that triggers an out-of-bounds write. This occurs because the parsing logic does not adequately validate the size or structure of the IFD tag data. The lack of proper input validation when handling the tag length and offset values allows the write operation to extend beyond the allocated memory region for image processing.
The attack complexity is rated as medium because creating a specifically crafted malicious image requires some degree of technical skill.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-58477 is 4.3 (Medium).
- CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
- 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 (C): None (N)
- Integrity (I): Low (L)
- Availability (A): None (N)
The CVSS score reflects that user interaction is required (opening a malicious image file) to trigger the vulnerability and that the impact is limited to potential integrity compromise (modification of data) or service denial. Confidentiality is not directly impacted.
Possible Impact
Successful exploitation of CVE-2025-58477 could lead to the following:
- Data Corruption: The out-of-bounds write could overwrite critical data structures, leading to system instability or application malfunction.
- Denial of Service (DoS): Repeated exploitation could crash the affected application or the entire device.
- Limited Code Execution: While the CVSS score suggests low impact on confidentiality and availability, out-of-bounds writes can be chained with other vulnerabilities in some cases to achieve remote code execution.
Mitigation or Patch Steps
The primary mitigation for CVE-2025-58477 is to update your Samsung device to the Security Maintenance Release (SMR) of December 2025 Release 1 or later. This release includes a patch that addresses the out-of-bounds write vulnerability.
To update your device, navigate to Settings > Software update > Download and install. Follow the on-screen instructions to download and install the latest available update.
As a general security precaution, avoid opening image files from untrusted sources.
