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 9 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 2026-10-26.

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 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

1. Monitor ravynsoft's official channels closely for security patches addressing CVE-2025-14309 and apply them promptly once available. 2. If you cannot patch yet, restrict network access to ravynos systems by implementing strict firewall rules and network segmentation to limit exposure to untrusted networks. 3. Deploy intrusion detection and prevention systems (IDS/IPS) to monitor for anomalous traffic patterns or repeated connection attempts that could indicate exploitation attempts. 4. Implement system monitoring to detect unexpected crashes or reboots of ravynos systems, enabling rapid incident response. 5. Consider isolating ravynos systems from critical production environments if feasible, to minimize impact in case of exploitation. 6. Educate system administrators on the vulnerability details and encourage vigilance for suspicious activity. 7. Review and harden network configurations to reduce attack surface, including disabling unnecessary services and ports on ravynos hosts. 8. Maintain regular backups of critical data and system states to facilitate recovery in case of denial of service incidents.

Description

NULL Pointer Dereference vulnerability in ravynsoft ravynos.This issue affects ravynos: through 0.5.2.

Impact

For European organizations, the primary impact of CVE-2025-14309 is the potential for denial of service on systems running ravynos OS. This could disrupt business operations, especially in environments relying on ravynos for specialized computing tasks or research. Although ravynos is not widely deployed in mainstream enterprise environments, organizations using it in critical infrastructure or development contexts could experience outages. The vulnerability does not compromise data confidentiality or integrity but can cause system crashes that affect availability. This may lead to operational downtime, loss of productivity, and potential cascading effects if ravynos systems are part of larger service chains. The absence of known exploits currently reduces immediate risk, but the ease of exploitation and lack of authentication requirements mean attackers could develop exploits rapidly. European entities with network-exposed ravynos systems are at higher risk, particularly those without robust network segmentation or intrusion detection capabilities.

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.
