CVE-2026-46196

CVE-2026-46196 describes a Linux kernel tracepoint regression: during a 0→1 transition, tracepoint_add_func() calls ext->regfunc() before installing a probe, and if func_add() fails (e.g., -ENOMEM), it previously did not call ext->unregfunc(), leaving behind side effects. The fix mirrors th...

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...
