| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: correctly handle malformed BPF_CORE_TYPE_ID_LOCAL relos\n\nIn case of malformed relocation record of kind BPF_CORE_TYPE_ID_LOCAL\nreferencing a non-existing BTF type, function bpf_core_calc_relo_insn\nwould cause a null pointer deference.\n\nFix this by adding a proper check upper in call stack, as malformed\nrelocation records could be passed from user space.\n\nSimplest reproducer is a program:\n\n r0 = 0\n exit\n\nWith a single relocation record:\n\n .insn_off = 0, /* patch first instruction */\n .type_id = 100500, /* this type id does not exist */\n .access_str_off = 6, /* offset of string \"0\" */\n .kind = BPF_CORE_TYPE_ID_LOCAL,\n\nSee the link for original reproducer or next commit for a test case." |
