  "details": "In the Linux kernel, the following vulnerability has been resolved:  bpf: don't rewrite bpf_fastcall patterns entered by a jump  mark_fastcall_pattern_for_call() must ensure that matched \"spill; call; fill\" instruction series is not interrupted by a jump. Otherwise the rewrite applied by bpf_remove_fastcall_spills_fills() is not sound.  Record the instructions targeted by jumps in insn_aux_data[*].jump_target when the CFG is built and use this flag to stop growing a pattern at such an instruction. Jumps to the first spill are fine.  Note that existing insn_aux_data[*].jmp_point field can't be reused, as it marks subprogram return instructions.",
