      "title": "sctp: hold socket lock when dumping endpoints in sctp_diag",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: hold socket lock when dumping endpoints in sctp_diag\n\nSCTP_DIAG endpoint dumping was traversing endpoint address lists without\nholding lock_sock(), while those lists could change concurrently via\nsocket operations (e.g., bindx changes). This creates a race where\nnla_reserve() counts addresses under RCU protection, but the subsequent\ncopy may see fewer entries, potentially leaking uninitialized memory to\nuserspace.\n\nFix this by:\n\n- Taking a reference on each endpoint during hash traversal\n- Moving socket operations (lock_sock()) outside read_lock_bh()\n- Serializing address list access during dump\n- Reworking sctp_for_each_endpoint() to support restart-based traversal\n  with (net, pos) tracking\n\nAlso:\n\n- Add WARN_ON_ONCE() for inconsistent address counts\n- Fix idiag_states filtering for LISTEN vs association cases\n- Skip dumping endpoints being freed (ep->base.dead)\n- Move dump position tracking into iterator, removing cb->args[4] and\n  its comment for sctp_ep_dump().,\n- Update the comment for cb->args[4] and remove the comment for unused\n  cb->args[5] for sctp_sock_dump().\n\nNote: traversal is restart-based and may re-scan buckets multiple times,\nbut this is acceptable due to small bucket sizes and required to support\nsleeping-safe callbacks.\n\nThis issue was reported by Nico Yip (@_cyeaa_) working with TrendAI Zero\nDay Initiative.",
