CVE-2026-9490
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAcer Care Center's ACCSvc service creates a Windows Named Pipe with an insecure Security Descriptor (weak ACL), allowing any authenticated local user to connect. An attacker with local access can send a specially crafted message (type 0x03) to the pipe, triggering a service crash (exit code 1067/ERROR_PROCESS_ABORTED), resulting in local denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Acer Care Center installationCheck for Acer Care Center in installed programs list via Windows Registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ or inspect Program Files\Acer\Acer Care Center folderAffected if Acer Care Center is found on the system
-
Determine installed versionRead the version from the executable at Program Files\Acer\Acer Care Center\Acer Care Center.exe, or check the version value in the uninstall registry keyAffected if Version is less than 4.00.3060 (e.g., 4.00.3000, 3.x.x.x)
-
Confirm ACCSvc service presenceOpen Services (services.msc) or run 'sc query ACCSvc' via command prompt to check if the ACCSvc service existsAffected if ACCSvc service exists on the system
-
Check ACCSvc service statusRun 'sc query ACCSvc' and verify the STATE shows RUNNINGAffected if ACCSvc service is currently running (vulnerability requires the service to be active)
-
Monitor for crash eventsCheck Windows Event Viewer under Windows Logs > Application for recent events from source 'ACCSvc' with exit code 1067 (ERROR_PROCESS_ABORTED)Affected if Recent crash events with exit code 1067 tied to ACCSvc are present
User is affected if Acer Care Center version below 4.00.3060 is installed AND the ACCSvc service is present and running on the system.

dbcve · scoped4.00.3060
Update Acer Care Center to the latest version to obtain the vendor patch that corrects the Named Pipe security descriptor. If the service is not required, consider disabling it to reduce attack surface.
4.00.3060 or later (latest available version)
- 1. Navigate to the official Acer support website (support.acer.com) and search for Acer Care Center
- 2. Download the latest version of Acer Care Center (version 4.00.3060 or later)
- 3. Run the downloaded installer as an administrator
- 4. Follow the on-screen installation prompts to complete the update
- 5. Restart the computer if prompted by the installer
- 6. After installation, verify the version by opening Acer Care Center and navigating to the About or Settings section to confirm version 4.00.3060 or later is installed
