      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf, cgroup: Fix storage null-ptr-deref after replacing prog\n\nSyzkaller reported a storage null-ptr-deref issue after replacing prog.\nThis occurs in the following scenario:\n1. prog A, an empty prog, is attached to a cgrp.\n2. prog B uses BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE and calls the\n   bpf_get_local_storage helper.\n3. link_update is called to replace prog A with prog B.\n\nThe reason is that __cgroup_bpf_replace fails to alloc and assign the\nrequired cgrp storage for the incoming replacement prog. Consequently,\nthe new prog inherits an uninit storage, leading to null-ptr-deref panic\nwhen kick the new prog.\n\nFix this by rejecting a link update if new_prog's cgroup storage is\nincompatible with link->prog.",
