Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-47407 is a memory corruption vulnerability that occurs while creating a process on the digital signal processor due to allocation failure at the kernel level. It is associated with CWE-367 and affects Qualcomm components, as documented in their security bulletin. The vulnerability received a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity with significant impacts on confidentiality, integrity, and availability.
A local attacker with low privileges can exploit this vulnerability with low attack complexity and no user interaction required. Successful exploitation leads to memory corruption, enabling high-level impacts such as unauthorized data access, modification, or denial of service on the affected DSP kernel.
Qualcomm's May 2026 security bulletin at https://docs.qualcomm.com/product/publicresources/securitybulletin/may-2026-bulletin.html details the vulnerability, including affected products and recommended mitigations or patches. Security practitioners should consult this advisory for specific remediation guidance.

Mitigating Controls (NIST 800-53 r5) AI
A reference monitor that is always invoked and analyzable structurally eliminates the non-atomic check-then-use pattern underlying TOCTOU.
Access enforcement that performs an atomic check-and-use decision directly stops the window in which a TOCTOU race can be exploited.
Process isolation limits the blast radius of a successful TOCTOU exploitation but does not remove the race itself.
