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: None: The vulnerable system can be exploited without any interaction from any user.
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: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Nov 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

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

Monitor Samsung’s official security advisories closely for patches or firmware updates addressing CVE-2025-54325 and apply them promptly once available.
Implement strict device management policies that restrict the use of vulnerable Samsung devices in sensitive or high-risk environments until patches are deployed.
Employ mobile device management (MDM) solutions to enforce security configurations, monitor device behavior, and restrict installation of untrusted applications that could exploit the vulnerability.
Use runtime protection and memory safety tools where possible to detect and prevent exploitation attempts targeting race conditions or out-of-bounds reads.
Educate users about the risks of connecting vulnerable devices to corporate networks and encourage cautious use of wearable devices that may process sensitive data.
Conduct regular security assessments and penetration testing focusing on mobile and wearable device security to identify potential exploitation vectors.
Limit local access to devices and enforce strong authentication to reduce the likelihood of attackers triggering the race condition.
Consider network segmentation to isolate devices running vulnerable processors from critical systems to contain potential breaches.

Description

An issue was discovered in VTS in Samsung Mobile Processor and Wearable Processor Exynos 1080, 1280, 2200, 1380, 1480, 2400, 1580, 2500, W920, W930, W1000. A race condition in the VTS driver results in an out-of-bounds read, leading to an information leak.

Impact

For European organizations, the impact of CVE-2025-54325 could be significant, particularly for those relying heavily on Samsung mobile and wearable devices in their operational environments. The information leak could expose confidential corporate data, user credentials, or proprietary information stored on or processed by these devices. This is especially critical for sectors such as finance, healthcare, government, and critical infrastructure, where data confidentiality is paramount. The wearable device vulnerability also raises concerns for organizations using such technology for employee monitoring or health data collection, potentially exposing personal or sensitive health information. The lack of available patches means organizations must rely on interim mitigations, increasing the window of exposure. Additionally, the vulnerability could be exploited as a foothold for lateral movement within corporate networks if attackers gain initial access via compromised devices. The broad range of affected processors means many Samsung devices in use across Europe could be vulnerable, increasing the potential attack surface. However, the complexity of exploitation and absence of known exploits in the wild somewhat limit immediate risk but do not eliminate the threat.
