## Source Location
sys/dev/drm/amd/powerplay/hwmgr/smu8_hwmgr.c:259-265

## Verdict
Source-confirmed: NULL deref in smu8_construct_max_power_limits_table when VBIOS omits S. 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_construct_max_power_limits_table at smu8_hwmgr.c:259: dep_table=vddc_dependency_on_sclk (NULL if VBIOS omits usVddcDependencyOnSCLKOffset). :262 dep_table->count derefs NULL -> panic at driver init. Crafted/corrupt VBIOS. Fix: check dep_table!=NULL.
