Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a potential NULL pointer dereference in the RDMA/irdma component of the Linux kernel. The function
in dev get() can return NULL, which will cause a failure when idev is dereferenced in in dev for each ifa rtnl(). A patch has been added to check for a NULL value in idev beforehand. This could potentially allow an attacker to cause a denial of service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
