FKIE_CVE-2026-9490

Vulnerability from fkie_nvd - Published: 2026-05-25 08:16 - Updated: 2026-07-23 11:10

Severity

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

A security vulnerability has been identified in Acer Care Center where the ACCSvc service creates a Named Pipe with a weak Security Descriptor. This vulnerability allows an authenticated local user to connect and send a specially crafted message (message type 0x03) to the pipe, causing the service to crash with exit code 1067 (ERROR_PROCESS_ABORTED). To mitigate this potential local service disruption, Acer requires users to update the software to the latest version.
