Abliterated models say yes 3-4x more but miss the real FreeBSD kernel bug entirely

evilsocket · x · 2026-09-04

Security researcher clearbluejar tested local open-weight models on a known FreeBSD kernel CVE and found that abliterated ("uncensored") builds judge findings far more loosely: they mark 3-4x more candidates VALID, wave through false positives the base model correctly rejects, yet the most aggressive build never surfaced the real bug across the whole directory. Chain-of-thought shows the model finding reasons to say no — then saying yes anyway. Key takeaway: abliteration strips skepticism along with refusal, hurting vulnerability research rather than helping.
