CVE-2025-47400 is a high-severity vulnerability affecting various Qualcomm firmware components, including pandeiro and sw6100 firmware. The issue arises from a cryptographic flaw that occurs while copying data to a destination buffer without appropriate size validation. This vulnerability has a CVSS score of 7.1, indicating a high level of risk to organizations using affected systems.
Organizations utilizing Qualcomm's affected firmware products face significant risks, as attackers may leverage this vulnerability to gain unauthorized access to sensitive data. The potential for high confidentiality and integrity impacts highlights the urgency for defenders to address this vulnerability promptly.
The vulnerability was published on April 6, 2026, and is classified as CWE-126, indicating a buffer over-read issue. With no known public exploit or proof of concept available, the risk remains theoretical but plausible, necessitating immediate attention from security teams.
Organizations should prioritize patching affected systems to mitigate the associated risks and enhance their security posture.
Vulnerability Details
CVE-2025-47400 is characterized as a cryptographic issue in Qualcomm firmware, resulting from the failure to validate the size of a destination buffer during data copying operations. The vulnerability is rated high with a CVSS score of 7.1, reflecting significant potential impacts on confidentiality and integrity, while availability remains unaffected.
The vulnerability affects multiple Qualcomm firmware components, including pandeiro_firmware, snapdragon_8_elite_gen_5_firmware, sw6100_firmware, and several others. The publication date for this vulnerability was on April 6, 2026.
Technical Analysis
The root cause of CVE-2025-47400 lies in improper handling of buffer sizes, leading to potential data exposure. The attack vector is local, meaning an attacker must have local access to exploit the vulnerability. The attack complexity is considered low, and only low privileges are required for exploitation, which further enhances the risk.
User interaction is not required, allowing an attacker to exploit the vulnerability without any action from the user. Given the high confidentiality and integrity impact, organizations must assess their exposure to this vulnerability and take necessary measures.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data, which could lead to data breaches and loss of trust. The potential blast radius is significant, as multiple firmware components are affected.
Given the CVSS score of 7.1, organizations should address this vulnerability in their priority patch cycle. The associated EPSS score of 0.000050000 indicates a low probability of exploitation in the wild, but this should not diminish the urgency of remediation efforts.
