CVE-2026-92511

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

Description A use-after-free issue exists in the RDMA core component. When accessing a Completion Queue (CQ) via the netlink path, the synchronization relies on rdma restrack get(). Because rdma restrack del() was previously called at the end of the ib destroy cq user() function, a window existed where the CQ remained accessible through restrack after vendor-specific resources were already freed.

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