Heap-Based Buffer Overflow in libimagecodec.quram.so Affects Samsung Products

CVE-2026-21095

What is CVE-2026-21095?

CVE-2026-21095 refers to a heap-based buffer overflow vulnerability found in the DNG decoder of the libimagecodec.quram.so component, which is used in various Samsung products. This vulnerability can be exploited by remote attackers to execute arbitrary code, potentially compromising the integrity and confidentiality of the affected systems. The issue arises when the buffer handling within the decoder fails to properly manage the allocation and deallocation of memory, allowing an attacker to overflow the buffer and overwrite adjacent memory. This could lead to unauthorized access, denial of service, or other malicious activity. Given that Samsung products are widely adopted across numerous consumer and corporate markets, the exploitation of this vulnerability could have broad ramifications for organizations reliant on these devices.

Potential impact of CVE-2026-21095

1. Remote Code Execution: The primary risk associated with CVE-2026-21095 is the possibility for remote attackers to execute arbitrary code on affected devices. This could enable them to take complete control over the system, leading to potential data breach or malware installation.

2. System Integrity Compromise: With successful exploitation, an attacker could manipulate system operations, resulting in unauthorized changes to files, processes, or even the overall system behavior, thereby undermining the trust and integrity of the organization’s technological environment.

3. Widespread Impact on Samsung Device Users: As this vulnerability affects multiple Samsung products, organizations using these devices could face widespread security risks. The impact can extend beyond individual devices to the entire network, especially in environments where security protocols and patches are not meticulously managed.
