  "title": "bpf: Fix overflow of jump offset in constant blinding",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  bpf: Fix overflow of jump offset in constant blinding  bpf_jit_blind_insn() rewrites \u0027if rX op imm goto off\u0027 into:    AX = imm ^ rnd   AX ^= rnd   if rX op AX goto off  and subtracts 2 from off when the jump is backward. off is s16, so -32767 and -32768 wrap and the jump goes 32767 insns forward, past the end of the prog. The jump is inside the patch, hence bpf_adj_branches() doesn\u0027t check it. The kernel crashes when such prog runs with bpf_jit_harden=2.  Return -ERANGE in such case. bpf_jit_blind_constants() fails the same way when blinding of other insns moves a jump out of range.",
