CVE-2026-80998 net: bnxt: ring the doorbell when SW USO exits early

In the Linux kernel, the following vulnerability has been resolved: net: bnxt: ring the doorbell when SW USO exits early When a burst of packets is handed down to the driver, the driver defers the doorbell to the end by setting txr-kickpending = 1. The normal TX path handles this, but the SW USO...

CVE-2026-74745

CVE-2026-74745 is a deadlock vulnerability in the bnxt network driver within the Linux kernel . When unregistering an IRQ affinity notifier, the driver synchronously waits for the callback while holding the netdev instance lock; the callback itself attempts to cancel work under the same lock, cau...

CVE-2026-74736

CVE-2026-74736 is a Linux kernel vulnerability in the net/sched cls_bpf classifier. The function cls_bpf_prog_from_efd() retrieved a SCHED_CLS program via bpf_prog_get_type_dev() without verifying that a device-bound (offloaded) BPF program's bound netdev matched the target TC netdev. This allowe...
