CVE-2026-15905

Heap corruption via Aura use-after-free

Published Jul 20, 2026 · Updated Jul 20, 2026

Use-after-free in Aura in Google Chrome before 150.0.7871.128 allows local users to corrupt heap memory through a malicious file. Public records identify Aura as the affected component but do not disclose the freed object's lifetime error, file format, or triggering code path because the Chromium issue remains restricted. Exploitation requires user interaction with a local file; successful heap corruption affects data confidentiality, integrity, and browser availability.
