Integrity: Low
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 2 Dec 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

European organizations should prioritize the following mitigations: 1) Monitor Samsung’s official security advisories and apply the SMR December 2025 Release 1 update or later as soon as it becomes available to remediate the vulnerability. 2) Implement strict controls on image file sources, restricting or scanning images received via email, messaging apps, or downloads to detect potentially malicious content. 3) Educate users about the risks of opening untrusted image files, emphasizing caution with unsolicited images or those from unknown sources. 4) Utilize mobile device management (MDM) solutions to enforce security policies, including restricting installation of apps that can process images from unverified sources. 5) Employ endpoint detection and response (EDR) tools capable of identifying anomalous application crashes or memory corruption events on mobile devices. 6) Consider network-level protections such as sandboxing or content disarm and reconstruction (CDR) for image files entering corporate environments. These targeted actions go beyond generic advice by focusing on controlling the attack vector (malicious images) and ensuring timely patch deployment.

Description

Out-of-bounds write in parsing IFD tag in libimagecodec.quram.so prior to SMR Dec-2025 Release 1 allows remote attackers to access out-of-bounds memory.

Impact

For European organizations, this vulnerability poses a moderate risk primarily to mobile device integrity. Samsung Mobile devices are widely used across Europe in both consumer and enterprise environments, including sectors reliant on mobile communications such as finance, healthcare, and government. Successful exploitation could allow attackers to corrupt memory, potentially leading to application crashes or unexpected behavior that might be leveraged in targeted attacks or to bypass security controls. While no direct confidentiality or availability impact is indicated, integrity compromises could facilitate further exploitation chains or data manipulation. The requirement for user interaction limits mass exploitation but does not eliminate risk from phishing or social engineering campaigns delivering malicious images. Organizations with mobile device management (MDM) systems controlling Samsung devices may face operational challenges if devices become unstable or compromised. The lack of current patches necessitates heightened vigilance until updates are deployed.
