Avast/AVG/Norton 26.7: sandbox escapes and WFP stream-parser crash (CVE-2026-80301–80303)
On Nov 6 2026 NVD published three Gen Digital (security@nortonlifelock.com) advisories affecting Avast, AVG and Norton Windows products before 26.7. CVE-2026-80301: the Avast sandbox virtualizes filesystem/registry but does not adequately restrict Task Scheduler COM, so a local low-privileged process inside the sandbox can schedule host tasks and escape to elevated host code execution. CVE-2026-80302: insufficient isolation in sandbox file virtualization lets a sandboxed process write arbitrary files to protected host locations and achieve host code execution. CVE-2026-80303: an integer underflow in the WFP stream parser can crash the system (DoS), triggerable remotely via filtered network traffic or locally. Update Avast/AVG/Norton to 26.7 or later.
