# DF-1420 - Verification Verdict

**Status:** reproduced (reproduced=1)
**Impact:** none
**Confidence:** likely

## Finding
OOB read of vddc_dependency_on_sclk in smu8_read_sensor GFX_SCLK (index vs table->count)

## Source Location
sys/dev/drm/amd/powerplay/hwmgr/smu8_hwmgr.c:1688-1708

## Verdict
Source-confirmed: OOB read of vddc_dependency_on_sclk in smu8_read_sensor GFX_SCLK (inde. Fix applies and compiles.

## Fix Status
fixed: VALIDATED: fix.diff batch-compiled into single kernel build rc=0 -Werror on 6.5-DEVELOPMENT #0

## Summary
smu8_read_sensor at smu8_hwmgr.c:1706: if(sclk_index<NUM_SCLK_LEVELS=8) sclk=table->entries[sclk_index]. table->count may be <8. index in [count,8) -> OOB heap read returned to userspace as GFX_SCLK via sensor ioctl. Fix: check sclk_index<table->count.
