Integrity: None
Availability: High

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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).

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 Qualcomm and device vendor advisories closely for official patches or firmware updates addressing CVE-2025-27041 and apply them promptly once available. 2. Implement strict access controls to limit local privilege escalation and reduce the risk of an attacker gaining the necessary local access to exploit the vulnerability. 3. Employ endpoint detection and response (EDR) solutions to monitor for anomalous behavior related to video firmware or chipset operations that could indicate exploitation attempts. 4. For automotive and embedded systems, coordinate with OEMs to schedule firmware updates and validate system stability post-patching. 5. Conduct regular security audits and vulnerability assessments on devices using affected Snapdragon chipsets to identify and remediate potential exposure. 6. Educate internal staff about the risks of local privilege misuse and enforce least privilege principles to minimize insider threat vectors. 7. Where possible, isolate critical systems using affected chipsets from untrusted networks or users to reduce attack surface. 8. Maintain robust incident response plans to quickly address any transient DoS events impacting video processing or connectivity services.

Description

CVE-2025-27041 is a medium-severity buffer over-read vulnerability (CWE-126) in Qualcomm Snapdragon chipsets affecting video packet processing. It can cause a transient denial of service (DoS) by crashing or disrupting the video firmware when processing crafted video packets. The vulnerability requires local privileges and no user interaction but has limited attack vector (local). It impacts a wide range of Snapdragon platforms including mobile, automotive, and connectivity chipsets. Although no known exploits are reported in the wild, the vulnerability could disrupt device availability temporarily. European organizations using devices with affected Snapdragon chipsets, especially in critical infrastructure or automotive sectors, may face operational disruptions. Mitigation involves applying vendor patches once available and monitoring device firmware updates closely. Countries with high adoption of Qualcomm Snapdragon devices and advanced automotive industries, such as Germany and France, are most likely to be affected. The CVSS score is 5.5, reflecting medium severity due to local access requirements and limited impact scope.

Impact

For European organizations, the primary impact of CVE-2025-27041 is the potential for transient denial of service in devices using affected Qualcomm Snapdragon chipsets. This could disrupt video processing functions in smartphones, automotive infotainment systems, and wireless communication devices. Critical sectors such as automotive manufacturing, transportation, telecommunications, and public safety could experience operational interruptions. In automotive contexts, disruption of video firmware could affect driver assistance systems or in-vehicle entertainment, potentially impacting safety and user experience. Telecommunications providers using affected modems might face service degradation. The requirement for local privileges limits remote exploitation, but insider threats or compromised devices could trigger the vulnerability. The widespread use of Qualcomm Snapdragon in consumer and industrial devices across Europe means the scope is broad, potentially affecting millions of endpoints. The absence of known exploits reduces immediate risk, but the vulnerability could be leveraged in targeted attacks or combined with other exploits. Organizations relying on video collaboration platforms or embedded systems with these chipsets should prioritize assessment and remediation to avoid service disruptions.

Summary

CVE-2025-27041 is a buffer over-read vulnerability classified under CWE-126 found in multiple Qualcomm Snapdragon chipsets and related platforms. The flaw occurs during the processing of video packets by the video firmware, where improper bounds checking leads to reading beyond the allocated buffer. This can cause a transient denial of service (DoS) condition, disrupting video processing capabilities temporarily. The vulnerability affects a broad range of Qualcomm products, including mobile platforms like Snapdragon 660, 680, 888 series, automotive modems, and various wireless connectivity chips (e.g., FastConnect 6900, QCA series). Exploitation requires local privileges (AV:L) with low attack complexity (AC:L) and no user interaction (UI:N), but privileges are necessary to trigger the flaw. The impact is limited to availability (A:H), with no confidentiality or integrity compromise. No public exploits have been reported yet, and Qualcomm has not published patches at the time of disclosure. The vulnerability was reserved in February 2025 and published in October 2025, indicating a recent discovery. The broad product impact suggests that many devices incorporating these chipsets could be vulnerable, including smartphones, automotive systems, and IoT devices. The transient DoS could disrupt critical services relying on video processing or connectivity. Given the complexity and requirement for local access, exploitation is less likely remotely but remains a concern for targeted attacks or insider threats.
