CVE-2025-37933

MEDIUM

Linux Kernel 6.4-6.6.89, 6.7-6.12.27, 6.13-6.14.5 - Use-After-Free in octeon_ep Device Reboot Handler

Title source: llm
STIX 2.1

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.
