Overview

CVE-2026-72282 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

KVM: Move kvm_io_bus_get_dev() locking responsibilities to callers

kvm_io_bus_get_dev() returns a device that is only matched by the

address, and nothing else. This can cause a lifetime issue if

the matched device is not the expected type, as by the time

the caller can introspect the object, it might be gone (the srcu

lock having been dropped).

Given that there is only a single user of this helper, the simplest

option is to move the locking responsibility to the caller, which

can keep the srcu lock held for as long as it wants.

Note that this aligns with other kvm_io_bus*() helpers, which

already require the srcu lock to be held by the callers.

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.
