CVE-2025-59616 Qualcomm, Inc. CVE debrief

A memory corruption vulnerability exists in an unspecified product due to improper handling of multiple IOCTL calls with the same buffer file descriptor input. This issue arises from accessing memory that has already been freed, potentially leading to system instability or code execution. The vulnerability is caused by a memory corruption issue when processing multiple IOCTL calls with the same buffer file descriptor input. This occurs because the system attempts to access memory that has already been freed. The Common Vulnerability Scoring System (CVSS) score for this vulnerability is 6.6, indicating a medium severity level. The CVSS vector is CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:L/I:H/A:L. System administrators and security professionals responsible for managing and securing systems that utilize the affected product should be aware of this vulnerability. Due to the limited information available, verifying the affected products and assessing the potential impact is crucial. Limited information is available about the affected products, and further investigation is needed to determine the full scope of the vulnerability.
