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

bpf: Disallow interpreter fallback for arena-related insns

Since the interpreter does not support the arena-related insns, interpreter fallback should not be allowed for these insns in core.c::__bpf_prog_select_runtime().

Currently, when the interpreter executes the arena ST/LDX/STX insns, it would hit the BUG_ON() in ___bpf_prog_run() at run time.

[ 2.579196] BPF interpreter: unknown opcode a2 (imm: 0x0) [ 2.579998] ------------[ cut here ]------------ [ 2.580652] kernel BUG at kernel/bpf/core.c:2349! [ 2.581314] Oops: invalid opcode: 0000 [#1] SMP PTI

Set jit_required as true when arena map is used in the prog to disallow interpreter fallback for arena-related insns.
