# DF-1937 VERDICT

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

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

**Mechanism:** rv730_populate_sclk_value L97-98 and rv730_populate_mclk_value L173-174 compute clk_s=reference_clock*5/(reference_divider*ss.rate) then clk_v=ss.percentage*fbdiv/(clk_s*10000) with no guard against s

**Citation:** `sys/dev/drm/radeon/rv730_dpm.c:97-174`

**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.
