CVE-2026-90207

CVE-2026-90207 is a race condition in the Linux kernel ALSA seq midi subsystem (snd_seq_midi). During input teardown, snd_midi_input_event() can still execute while a rawmidi substream is closing, causing the trigger state to become out-of-step. After rawmidi_release_priv() sets rfile->rmidi t...

CVE-2026-90186

CVE-2026-90186 affects the Linux kernel null_blk driver. When the module is loaded with shared_tags enabled, a per-device resize of submit_queues or poll_queues via configfs calls blk_mq_update_nr_hw_queues() on the shared tag set, shrinking hardware queue contexts. The resulting NULL hardware co...
