CVE-2022-50220

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

Description A use-after-free issue has been identified in the Linux kernel's usbnet component. This issue arises when the usbnet deferred kevent() work is awaited after the unregister netdev() call, potentially causing netif carrier {on,off}() to operate on an unregistered netdev and linkwatch event() to run after free netdev(). The problem originated from a change made in 2003 to prevent a deadlock, but it introduced the use-after-free issue in USB Ethernet drivers.

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