CVE-2022-48742 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-modules-partner package and not the kernel-modules-partner package as distributed by Centos.
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.
