What is CVE-2026-23262?

A memory corruption vulnerability exists in the Linux kernel's handling of network interface card (NIC) statistics reporting. The gve driver and NIC share a memory region for stats reporting. When the number of queues is altered, the driver's stats region is resized. An increase in the queue count may lead the NIC to overwrite memory beyond this region, causing corruption. Conversely, a decrease creates a discrepancy that results in inaccurate stats reporting. This issue has been mitigated by allocating the stats region with a maximum size and adjusting the NIC's offset calculation accordingly.
