# DF-1910 VERDICT

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

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

**Mechanism:** i2s_pdata kcalloc L242 (3*sizeof i2s_platform_data) passed by pointer to acp_cell[1..3].platform_data L325/331/337 consumed (copied) by mfd_add_hotplug_devices L340. No kfree(i2s_pdata) on success ret

**Citation:** `sys/dev/drm/amd/amdgpu/amdgpu_acp.c:242-464`

**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.
