Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to the rtnl newlink() function in the Linux kernel, which can potentially trigger use-after-free due to the replay logic. This could allow an attacker to elevate their privileges. The problem is resolved by refreshing master dev/m ops in rtnl newlink() and clearing master dev and m ops inside the loop in case of replay.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
