CVE-2026-98355 is a vulnerability in Linux Kernel
Published on October 6, 2026
RDMA/rtrs: guard against null kobj name
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.
