execute in all kinds of contexts and when a program\nrunning in a non-preemptible context uses the bpf_send_signal() kfunc,\nit will cause issues because this kfunc can sleep.\nChange `irqs_disabled()` to `!preemptible()`.","state":0,"publishedAt":"2025-02-27T02:07:34.114+00:00","modifiedAt":"2026-10-15T01:03:49.601+00:00","affected":[{"ecosystem":"Vendor
