Overview

CVE-2026-23262 is a high-severity vulnerability. It was published on March 18, 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:

gve: Fix stats report corruption on queue count change

The driver and the NIC share a region in memory for stats reporting.

The NIC calculates its offset into this region based on the total size

of the stats region and the size of the NIC's stats.

When the number of queues is changed, the driver's stats region is

resized. If the queue count is increased, the NIC can write past

the end of the allocated stats region, causing memory corruption.

If the queue count is decreased, there is a gap between the driver

and NIC stats, leading to incorrect stats reporting.

This change fixes the issue by allocating stats region with maximum

size, and the offset calculation for NIC stats is changed to match

with the calculation of the NIC.

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.
