Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-47343 is a memory corruption vulnerability stemming from CWE-822 (Untrusted Pointer Dereference) that occurs while processing a video session to set video parameters. It affects Qualcomm components, as detailed in the vendor's January 2026 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 high impact potential with local access vector, low attack complexity, and low privileges required.
A local attacker with low privileges can exploit this vulnerability without user interaction by triggering the faulty video parameter processing. Successful exploitation enables high-impact outcomes, including unauthorized access to sensitive data (confidentiality), modification of system state (integrity), and denial of service or system crashes (availability), potentially leading to full local privilege escalation or compromise of the affected component.
Qualcomm's January 2026 security bulletin at https://docs.qualcomm.com/product/publicresources/securitybulletin/january-2026-bulletin.html provides details on affected products and recommends applying vendor-supplied patches to mitigate the issue. Practitioners should review the bulletin for specific firmware or driver updates tailored to impacted Snapdragon platforms or multimedia subsystems.

Mitigating Controls
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.
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.
