Improper Access Control in V-Secure Jingyun Antivirus ZyArk.sys Kernel Driver

IdentifiersCVE-2026-19195CWE-284· Improper Access Control

CVE-2026-19195 is a local vulnerability in V-Secure Jingyun Antivirus 2.4.2.39 affecting an unspecified function within the ZyArk.sys kernel driver component. The flaw is characterized as improper access control, indicating that the driver does not adequately restrict access to a privileged operation or interface exposed from kernel mode. Because the vulnerable component is a kernel driver, successful exploitation could allow a local attacker to invoke functionality that should be restricted to trusted or higher-privileged contexts. Public exploit disclosure indicates that exploit details are available.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation may allow a local attacker to bypass intended security restrictions enforced by the affected kernel driver and gain unauthorized access to privileged functionality. Given the vulnerability resides in a kernel-mode component, impact may include elevation of privileges or other unauthorized capabilities on the affected host, depending on how the exposed driver functionality can be abused.

Mitigation

If you can’t patch tonight, do this now.

Restrict local access to affected systems and minimize the number of users with interactive logon capability. Limit administrative and privileged local access, monitor for suspicious interaction with kernel drivers, and isolate systems running the affected software where feasible. Until a vendor fix is available, disabling or uninstalling the affected product is the most direct risk-reduction measure if business requirements permit.

Remediation

Patch, then assume compromise.

Upgrade V-Secure Jingyun Antivirus to a vendor-fixed release once one becomes available. If no patched version is available, remove or disable the affected V-Secure Jingyun Antivirus 2.4.2.39 deployment on systems where doing so is operationally feasible. Validate that the vulnerable kernel driver is no longer loaded after remediation.
