CVE-2026-46181 RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event()

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx4: Fix mis-use of RCU in mlx4srqevent Sashiko points out the radixtree itself is RCU safe, but nothing ever frees the mlx4srq struct with RCU, and it isn't even accessed within the RCU critical section. It also will crash...

CVE-2026-46181

Summary: CVE-2026-46181 concerns the Linux kernel RDMA/mlx4 component. The root cause is improper use of Read-Copy Update (RCU) in mlx4_srq_event(), which could allow a race where an event is delivered before the srq object is fully initialized, potentially crashing the system. The documented fix...
