  "title": "bpf: Reject resilient lock operations in rbtree callbacks",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  bpf: Reject resilient lock operations in rbtree callbacks  __bpf_rbtree_add() keeps parent and link pointers live across calls to the program-supplied comparison callback. The verifier therefore requires the root\u0027s lock to remain held throughout the callback.  The helper path enforces this rule for bpf_spin_lock() and bpf_spin_unlock(), but the resilient lock kfunc argument path does not. Since resilient locks may protect BPF rbtree roots, a callback can release the root lock and let another CPU remove and free the node referenced by the in-progress tree walk. The walk then resumes using freed pointers.  Reject resilient lock kfuncs in an rbtree comparison callback, matching the existing policy for the spin lock helpers. Resilient-lock-protected trees remain valid when their comparison callbacks leave lock state alone.",
