Overview

Affected versions of this package are vulnerable to Improper Control of a Resource Through its Lifetime due to improper management of the net_device lifecycle during the bind and unbind phases of USB gadget function instances. An attacker can cause dangling sysfs symlinks and inconsistent device states by repeatedly binding and unbinding the gadget, potentially leading to resource leaks or system instability.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
