# DF-1934 VERDICT

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

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

**Mechanism:** dce4_hdmi_set_color_depth L342 connector=radeon_get_connector_for_encoder(encoder) no NULL check before connector->name in DRM_DEBUG L355/361/367. radeon_get_connector_for_encoder returns NULL when ac

**Citation:** `sys/dev/drm/radeon/evergreen_hdmi.c:342-367`

**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.
