CVE-2026-23262
Full vulnerability record from the local CVENow database.
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.

Si el recuento de colas se incrementa, la NIC puede escribir más allá\ndel final de la región de estadísticas asignada, causando corrupción de memoria.\nSi el recuento de colas se disminuye, hay una brecha entre las estadísticas del controlador\ny de la NIC, lo que lleva a un informe de estadísticas incorrecto.\n\nEste cambio soluciona el problema asignando la región de estadísticas con el tamaño\nmáximo, y el cálculo del desplazamiento para las estadísticas de la NIC se cambia para que\ncoincida con el cálculo de la NIC."
