CVE-2022-48742

HIGH

Linux Kernel Use-After-Free in rtnetlink __rtnl_newlink

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: rtnetlink: make sure to refresh master_dev/m_ops in __rtnl_newlink() While looking at one unrelated syzbot bug, I found the replay logic in __rtnl_newlink() to potentially trigger use-after-free. It is better to clear master_dev and m_ops inside the loop, in case we have to replay it.
