In the Linux kernel, the following vulnerability has been resolved:

bpf: Disallow interpreter fallback for gotox insn

The interpreter does not recognize the BPF_JMP|BPF_JA|BPF_X insn, which is used for insn_array map. Thereafter, it would hit the BUG_ON() in ___bpf_prog_run() at run time.

[ 2.563726] BPF interpreter: unknown opcode 0d (imm: 0x0) [ 2.564557] ------------[ cut here ]------------ [ 2.565206] kernel BUG at kernel/bpf/core.c:2349! [ 2.565882] Oops: invalid opcode: 0000 [#1] SMP PTI

Set jit_required as true when insn_array map is used in the prog in order to disallow interpreter fallback for gotox insn in core.c::__bpf_prog_select_runtime().
