CVE-2026-93110

A flaw was found in the Linux kernel's RDMA core component. A race condition exists where RCU Read-Copy-Update callbacks, specifically putgidndev, can be invoked after the ibcore module has been unloaded. This occurs because stopping workqueues does not drain already queued callbacks, allowing RC...
