- bpf: fix check for attempt to corrupt spilled pointer
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
bpf: fix check for attempt to corrupt spilled pointer
When register is spilled onto a stack as a 1/2/4-byte register, we set slottype[BPFREGSIZE - 1] (plus potentially few more below it, depending on actual spill size). So to check if some stack slot has spilled register we need to consult slottype[7], not slot_type[0].
To avoid the need to remember and double-check this in the future, just use isspilledreg() helper.
