Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the atm/clip subsystem where a null pointer dereference may occur in the
to atmarpd() function. This issue arises because to atmarpd() can be called without proper Real-Time Network Layer (RTNL) protection, particularly during unsleepable operations like clip neigh solicit() and neigh ops->solicit(). The vulnerability exists due to a lack of RTNL dependency around atmarpd. A private mutex and Read-Copy Update (RCU) mechanism have been implemented to protect access to atmarpd within to atmarpd().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
