This vulnerability (CVE-2025-47408) involves memory corruption in Qualcomm Snapdragon devices caused by untrusted pointer dereference when an IOCTL call is made with invalid input/output buffers by another driver. It affects a wide range of Snapdragon platforms and related hardware components. The CVSS 3.1 base score is 7.8, reflecting high impact with local attack vector, low attack complexity, low privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No vendor advisory or patch information is currently available, and no exploits are known in the wild.

Successful exploitation could lead to memory corruption, potentially allowing an attacker with local privileges to compromise confidentiality, integrity, and availability of the affected device. The vulnerability requires local access and low complexity to exploit, but no user interaction. Given the broad range of affected Snapdragon platforms, impacted devices could experience significant security breaches if exploited.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit local access to trusted users and monitor for unusual driver interactions. Avoid running untrusted code or drivers that could invoke the vulnerable IOCTL calls.
