# DF-1877 VERDICT

**Verdict:** REPRODUCED (source-confirmed)

**Impact:** Low (driver-level NULL deref / OOB / leak / DoS — hardware-gated)

**Mechanism:** radeon_irq_kms_init registers 3 deferred works L313-315 hotplug_work dp_work audio_work. radeon_irq_kms_fini L336-347 only calls flush_delayed_work(hotplug_work) L345 no flush_work(dp_work) no flush_w

**Citation:** `sys/dev/drm/radeon/radeon_irq_kms.c:313-346`

**Fix:** Applied fix.diff — compiles in batch kernel build (rc=0, -Werror).

**Verification method:** Source-only line-by-line trace of cited path:line. Low-severity driver bug; PoC trigger requires specific hardware or root context. Confirmed the cited vulnerable pattern exists in source.
