Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-47408 is a memory corruption vulnerability (CWE-822: Untrusted Pointer Dereference) triggered when another driver issues an IOCTL call with invalid input or output buffers. It affects components in Qualcomm products, as documented in the vendor's security bulletin.
The vulnerability carries 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 it can be exploited by a local attacker with low privileges. Exploitation requires low complexity and no user interaction, allowing the attacker to achieve high impacts on confidentiality, integrity, and availability through memory corruption.
Qualcomm's May 2026 security bulletin at https://docs.qualcomm.com/product/publicresources/securitybulletin/may-2026-bulletin.html provides details on affected products and recommended mitigations or patches.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover instances where untrusted data is turned into a pointer and dereferenced.
Validating all information inputs stops untrusted values from being accepted and converted into dereferenceable pointers.
Secure engineering principles require memory-safe design and coding that structurally avoids buffer-boundary violations.
Memory-protection mechanisms limit the damage from an invalid pointer dereference without stopping the root coding flaw.

Security testing can detect pointer-dereference flaws before release.
Secure development lifecycle includes pointer-safety practices that reduce untrusted pointer dereference risk.
Application security requirements can mandate validation of pointers obtained from untrusted sources.
Secure architecture principles discourage direct use of untrusted values as pointers.
Secure coding standards explicitly forbid dereferencing pointers derived from untrusted input.
