Integrity: High
Availability: None

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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

CVE published 2 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed

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

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 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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.

AI-suggested

Monitor Qualcomm advisories closely for official patches or firmware updates addressing CVE-2025-47378 and apply them promptly across all affected devices.
Implement strict access controls and privilege separation on devices using affected Snapdragon platforms to limit the ability of low-privileged processes to access sensitive system components.
Employ runtime integrity monitoring and anomaly detection to identify unauthorized access attempts to boot loader or cryptographic material.
Use hardware-backed security features such as Trusted Execution Environments (TEE) and secure boot to reinforce isolation between HLOS and boot loader components.
For enterprise deployments, enforce device management policies that restrict installation of untrusted software and monitor device firmware integrity.
Coordinate with device manufacturers and vendors to ensure timely updates and security patches are integrated into device firmware.
Consider network segmentation and endpoint detection to reduce the attack surface and detect lateral movement if exploitation occurs.
Educate security teams about the specific nature of this vulnerability to enhance incident response readiness.

Description

Cryptographic Issue when a shared VM reference allows HLOS to boot loader and access cert chain.

Impact

The vulnerability can lead to unauthorized disclosure of sensitive cryptographic information, including certificate chains used in secure boot processes. This exposure compromises the confidentiality and integrity of the device's trusted computing base, potentially allowing attackers with low privileges to escalate their control or bypass security mechanisms. The compromised certificate chain could enable attackers to inject malicious firmware or software, undermining device trustworthiness and enabling persistent attacks. Given the extensive deployment of affected Snapdragon platforms in mobile phones, AR devices, IoT, and automotive systems, the impact is broad and severe. Organizations relying on these devices for critical communications, data processing, or operational technology could face data breaches, intellectual property theft, or operational disruptions. The lack of user interaction required and the relatively low complexity of exploitation increase the risk of targeted attacks, especially in environments where attackers can gain low-level access. Although availability is not directly affected, the integrity and confidentiality breaches can lead to downstream impacts on system stability and security posture.
