What to do

AI-suggested

A fix is available in the Linux kernel that replaces direct calls to the device-specific ndo_stop function with calls to dev_close during device reboot and driver unload. Users should update to the fixed kernel version once available to prevent host hangs related to this issue.

Description

A vulnerability in the Linux kernel's octeon_ep driver caused a host hang during device reboot due to improper resource freeing when the driver is unloaded. The issue arises because the device-specific ndo_stop function is called multiple times, freeing resources twice. The fix involves calling dev_close instead of ndo_stop directly, ensuring proper cleanup and preventing the host hang.
