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. CREATE(Triage):(User=admin) CVE-2022-48742 (https://nvd.nist.gov/vuln/detail/CVE-2022-48742)
