Overview

CVE-2026-62426 is a high-severity vulnerability. It was published on July 28, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

[This CNA information record relates to multiple CVEs; the

text explains which aspects/vulnerabilities correspond to which CVE.]

To manage the system, sysctl and platform operations are used by the

control domain or a possible Xenstore domain. Some of these operations

may not be executed in parallel, so a system-wide lock each is used.

The way those locks are acquired is, however, not providing any fairness.

Furthermore, with XSM/Flask in use, the lock acquire will, for some

operations, occur ahead of any permission checking.

The sysctl issue is CVE-2026-62426.

The platform-op issue is CVE-2026-62427.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
