CVE-2026-98355

Full vulnerability record from the local CVENow database.

Description

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.
