# DF-0228 -- Low

## Verdict: REPRODUCED (source-confirmed)

REAL: gpt->hdr_lba_table is uint64 but table_lba is uint32_t and decoded with le32toh (line 133); on >=2TB disks the partition-table LBA is silently truncated. Confirmed in source.

## Fix
Declare table_lba as uint64_t and use le64toh. Matches finding proposal.

## Validation
Combined 60-finding fix kernel (findings/poc/_low_merged.patch) built `make -j6 nativekernel KERNCONF=X86_64_GENERIC` => rc=0, 0 errors, -Werror. fix_status=fixed.
