CVE-2025-22116

In the Linux kernel, the following vulnerability has been resolved: idpf: check error for register_netdev() on init Current init logic ignores the error code from register_netdev(), which will cause WARN_ON() on attempt to unregister it, if there was one, and there is no info for the user that the creation of the netdev failed. WARNING: CPU: 89 PID: 6902 at net/core/dev.c:11512 unregister_netdevice_many_notify+0x211/0x1a10 ...

On removal make sure to check VPORT_REG_NETDEV flag prior to calling unregister and free on the netdev. Add local variables for idx, vport_config and netdev for readability.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: idpf: error de verificación para register_netdev() en init La lógica de init actual ignora el código de error de register_netdev(), lo que provocará WARN_ON() al intentar anular su registro, si lo hubiera, y no hay información para el usuario de que falló la creación de netdev. ADVERTENCIA: CPU: 89 PID: 6902 en net/core/dev.c:11512 unregister_netdevice_many_notify+0x211/0x1a10 ... [ 3707.563641] unregister_netdev+0x1c/0x30 [ 3707.563656] idpf_vport_dealloc+0x5cf/0xce0 [idpf] [ 3707.563684] idpf_deinit_task+0xef/0x160 [idpf] [ 3707.563712] idpf_vc_core_deinit+0x84/0x320 [idpf] [ 3707.563739] idpf_remove+0xbf/0x780 [idpf] [ 3707.563769] pci_device_remove+0xab/0x1e0 [ 3707.563786] device_release_driver_internal+0x371/0x530 [ 3707.563803] driver_detach+0xbf/0x180 [ 3707.563816] bus_remove_driver+0x11b/0x2a0 [ 3707.563829] pci_unregister_driver+0x2a/0x250 Introduce una comprobación de errores y registra el número de puerto virtual y el código de error. Al eliminar, asegúrese de comprobar el indicador VPORT_REG_NETDEV antes de ejecutar las funciones unregister y free en netdev. Agregue variables locales para idx, vport_config y netdev para facilitar la lectura.
