      "title": "bpf: Skip unsettled links in link iterator",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Skip unsettled links in link iterator\n\nbpf_link_prime() inserts a link into link_idr before anon_inode_getfile()\nsucceeds and before bpf_link_settle() publishes the ID in link->id.\nbpf_link_by_id() treats such an ID-zero link as unsettled, but the link\niterator takes a reference without this check.\n\nIf anon_inode_getfile() then fails, the creator removes the ID and frees\nits still-private link directly.  The iterator is left with a dangling\nreference and its next bpf_link_put() accesses freed memory.\n\nTreat ID-zero entries as transient in bpf_link_get_curr_or_next(), just as\nbpf_link_by_id() does.\n\n  BUG: KASAN: slab-use-after-free in bpf_link_put\n  Write of size 8 by task exp/384\n  Call Trace:\n  bpf_link_put                    kernel/bpf/syscall.c:3372\n  bpf_link_seq_next               kernel/bpf/link_iter.c:33\n  bpf_seq_read                    kernel/bpf/bpf_iter.c:158\n  vfs_read                        fs/read_write.c:572\n  ksys_read                       fs/read_write.c:716\n  do_syscall_64                   arch/x86/entry/syscall_64.c:84\n  entry_SYSCALL_64_after_hwframe  arch/x86/entry/entry_64.S:121\n  Kernel panic - not syncing: KASAN: panic_on_warn set ...",
