# DF-1914 VERDICT

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

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

**Mechanism:** drm_agp_info_ioctl L79 struct drm_agp_info info; on stack without zeroing. drm_agp_info L62-70 fills 9 named fields covering bytes 0..51 of 56-byte struct on amd64 (two unsigned short at offset 48/50 

**Citation:** `sys/dev/drm/drm_agpsupport.c:62-86`

**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.
