  "description": "In the Linux kernel, the following vulnerability has been resolved:  bpf: Disallow interpreter fallback for BPF_ADDR_PERCPU insn  The BPF_MOV64_PERCPU_REG insn requires JIT to emit native code to for \u0027dst_reg = src_reg \u002B \u003Cpercpu_base_off\u003E\u0027.  However, the interpreter ignores the \u0027off\u0027 at its ALU64_MOV_X label. The \u0027off\u0027 indicates the insn is BPF_MOV64_PERCPU_REG insn. Then, when the interpreter loads memory from the register, it will hit a page fault.  [    2.545572] BUG: unable to handle page fault for address: ffffffffacaaf034 [    2.546485] #PF: supervisor read access in kernel mode [    2.547167] #PF: error_code(0x0000) - not-present page [    2.547850] PGD 134e63067 P4D 134e63067 PUD 134e64063 PMD 10021c063 PTE 800ffffeca550062 [    2.548912] Oops: Oops: 0000 [#1] SMP PTI  Set jit_required as true in order to disallow interpreter fallback in core.c::__bpf_prog_select_runtime(), if any BPF_ADDR_PERCPU insn is patched to the prog.  BTW, rename the helper bpf_map_supports_cpu_flags() to bpf_map_is_percpu_map().",
