      "title": "bpf: Reject programs with inlined helpers if JIT is not available",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Reject programs with inlined helpers if JIT is not available\n\nWhen an architecture (such as LoongArch, ARM64, and RISC-V) implements\nbpf_jit_inlines_helper_call(), the verifier skips rewriting the helper\ncall offset (insn->imm) in bpf_do_misc_fixups(). This is because the\nhelper is expected to be inlined by the JIT compiler later. Therefore,\ninsn->imm remains as the raw helper enum ID.\n\nHowever, if JIT is disabled at runtime (net.core.bpf_jit_enable=0) or\nif JIT compilation fails dynamically (e.g., due to OOM), the program\nfalls back to the BPF interpreter.\n\nWhen the interpreter executes (__bpf_call_base + insn->imm) with the\nunpatched raw ID, it jumps into an invalid address space, triggering\nan instruction alignment fault or a kernel panic.\n\nAlthough these helpers have valid C implementations in the kernel, the\nomission of offset rewriting makes runtime interpreter fallback fatal.\n\nFix this by setting 'prog->jit_required = 1' when helper call rewriting\nis skipped for JIT inlining. This ensures that such programs are safely\nrejected if JIT is not available, preventing the runtime kernel panic.",
