"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Keep dynamic inner array lookups nullable\n\nAn ARRAY_OF_MAPS can use an array created with BPF_F_INNER_MAP as its\ninner map template. A concrete inner array with a different max_entries\nvalue can then replace the template.\n\nAfter a successful outer map lookup, the verifier represents the\nresulting map pointer using the inner map template. Const-key lookup\nnullness elision consequently uses the template max_entries even though\nthe runtime helper uses the concrete inner map max_entries.\n\nDo not elide lookup result nullness for maps marked with BPF_F_INNER_MAP,\nbecause the template max_entries does not prove that the key is in bounds\nfor the concrete runtime map."
