CVE-2026-53286

CVE-2026-53286 affects the Linux kernel IDPF driver: when auxiliary_device_add() fails in idpf_plug_vport_aux_dev() or idpf_plug_core_aux_dev(), the error path uninitializes the auxiliary device in a way that can trigger a use-after-free and a double free of the iadev object. The issue arises bec...
