In the Linux kernel, the following vulnerability has been resolved: bpf: handle jset (if a & b ...) as a jump in CFG computation BPF_JSET is a conditional jump and currently verifier.c:can_jump() does not know about that. This can lead to incorrect live registers and SCC computation. E.g. in the following example: 1: r0 = 1; 2: r2 = 2; 3: if r1 & 0x7 goto +1; 4: exit; 5: r0 = r2; 6: exit; W/o this fix insn_successors(3) will return only (4), a jump to (5) would be missed and r2 won't be marked as alive at (3).

Are you affected?

Enter the version you run. The result uses only the ranges stored on this record.
