CVE-2026-64033

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the RDMA/rtrs component during the cleanup process of path file creation. In the error path of the rtrs srv create path files() function, the system may call kobject put() on the srv path->kobj object before calling rtrs srv destroy once sysfs root folders(). Because kobject put() can trigger the rtrs srv release() callback and free the srv path memory, the subsequent call to rtrs srv destroy once sysfs root folders() attempts to access the already freed srv path to reach srv path->srv, leading to a memory corruption or system crash.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
