I constantly get a kernal panic on multiple machines under heavy load of the sort of trying to interlock destroyed mutex from within, according to the backtrace, com.metakine.handsoff.driver. I'm wondering if it's exploitable.
- jmah 8y agoIs that a third party kernel extension? Sounds like a buggy one if so, and if it’s this <https://www.oneperiodic.com/products/handsoff/> https://www.oneperiodic.com/products/handsoff/> then it might be lessening security instead of increasing it.
- anonlapwarmer 8y agoYeap. I wouldn't say lessening unilaterally but with the nuance of changing the attack surface in different areas. IIRC "Hands Off!" is a firewall and an app firewall that can selectively limit disk and network access.
- anonlapwarmer 8y agoNot sure about the vulnerability of it, but it sounds like an unhandled race-condition.
