Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel’s wilc1000 module related to network device unregistration. Specifically, the wilc netdev ifc init() function lacks a call to unregister netdev() in its error handling path. This can lead to a kernel bug, indicated by an invalid opcode error, when alloc ordered workqueue() fails. The issue occurs because the cfg80211 unregister netdevice() function or unregister netdev() is not called during error handling, potentially causing resource leaks or instability.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
