CVE-2025-37933 Information

Description

In the Linux kernel the following vulnerability has been resolved:

octeon_ep: Fix host hang issue during device reboot

When the host loses heartbeat messages from the device the driver calls the device-specific ndo_stop function which frees the resources. If the driver is unloaded in this scenario it calls ndo_stop again attempting to free resources that have already been freed leading to a host hang issue. To resolve this dev_close should be called instead of the device-specific stop function.dev_close internally calls ndo_stop to stop the network interface and performs additional cleanup tasks. During the driver unload process if the device is already down ndo_stop is not called.
