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.

Is that a third party kernel extension? Sounds like a buggy one if so, and if it’s this <https://www.oneperiodic.com/products/handsoff/> then it might be lessening security instead of increasing it.

Yeap. 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.

Not sure about the vulnerability of it, but it sounds like an unhandled race-condition.
