In the Linux kernel, the following vulnerability has been resolved:

RDMA/rtrs: guard against null kobj name

In the client, if init_path() errors, the callee tries to clean up with rtrs_clt_close_conns(). However, this can lead to calling the event tracing code with clt_path->kobj->name being NULL and thus causing a null pointer dereference when trying to copy from it.

This just adds a guard to check that the name is not NULL before copying from it. The server appears to have a similar pattern.
