Descriptions

In the Linux kernel, the following vulnerability has been resolved:

bpf: Add BPF_PROG_TYPE_CGROUP_SKB attach type enforcement in BPF_LINK_CREATE

bpf_prog_attach uses attach_type_to_prog_type to enforce proper
attach type for BPF_PROG_TYPE_CGROUP_SKB. link_create uses
bpf_prog_get and relies on bpf_prog_attach_check_attach_type
to properly verify prog_type <> attach_type association.

Add missing attach_type enforcement for the link_create case.
Otherwise, it's currently possible to attach cgroup_skb prog
types to other cgroup hooks.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: bpf: agregue la aplicación del tipo de archivo adjunto BPF_PROG_TYPE_CGROUP_SKB en BPF_LINK_CREATE bpf_prog_attach usa adjunto_type_to_prog_type para aplicar el tipo de archivo adjunto adecuado para BPF_PROG_TYPE_CGROUP_SKB. link_create usa bpf_prog_get y se basa en bpf_prog_attach_check_attach_type para verificar correctamente la asociación prog_type &lt;&gt; adjunto_tipo. Agregue la aplicación de adjunto_tipo faltante para el caso link_create. De lo contrario, actualmente es posible adjuntar tipos de programa cgroup_skb a otros enlaces de cgroup.
