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: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Sep 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

Given the absence of official patches at the time of disclosure, European organizations should adopt a multi-layered mitigation approach. First, they should monitor official Google security advisories and device manufacturer updates closely to apply patches as soon as they become available. Until patches are released, organizations should limit exposure by restricting network access to Android devices, especially from untrusted or public networks, using network segmentation and firewall rules. Employing mobile device management (MDM) solutions can help enforce security policies, restrict installation of untrusted applications, and remotely manage device configurations to reduce attack surfaces. Organizations should also educate users about the risk and encourage them to avoid installing unknown or suspicious applications that might exploit this vulnerability. Where possible, disabling unnecessary services or network interfaces on Android devices can reduce the attack vectors. For critical environments, consider deploying intrusion detection systems (IDS) or endpoint detection and response (EDR) solutions capable of identifying anomalous behavior indicative of exploitation attempts. Finally, organizations should prepare incident response plans to quickly address potential DoS incidents affecting Android devices.

Description

In TBD of TBD, there is a possible DoS due to a missing null check. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.

Impact

For European organizations, the impact of CVE-2025-36894 could be substantial, especially for those relying heavily on Android devices for business operations, communications, or critical infrastructure monitoring. A successful exploitation could lead to widespread device outages, disrupting employee productivity, communication channels, and access to enterprise applications. In sectors such as finance, healthcare, and public services, where Android devices may be used for secure communications or data access, a denial of service could delay critical operations and impact service delivery. Additionally, organizations that provide Android-based services or manage fleets of Android devices (e.g., logistics, retail, or field services) could face operational disruptions and increased support costs. The fact that no user interaction or elevated privileges are required increases the risk of automated or large-scale attacks, potentially affecting many devices simultaneously. Furthermore, the lack of immediate patches means organizations must implement interim mitigations to reduce exposure. The vulnerability also poses risks to consumer privacy and trust if devices become unstable or unusable, indirectly affecting organizations that rely on consumer-facing Android apps or services.

Base weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #13OWASP Top 10 A10:2025: Mishandling of Exceptional Conditions (opens in a new tab)
The product dereferences a pointer that it expects to be valid but is NULL.
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished.
Requirements
Select a programming language that is not susceptible to these issues.
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
