CVE-2026-68324

dmar_latency_disable() intends to zero out only the single latency_statistic entry for the given type, but the memset size was computed as sizeof(*lstat) * DMAR_LATENCY_NUM, which clears the entire array starting from &lstat[type].

When type > 0, this writes beyond the end of the allocated array, corrupting adjacent memory.

Fix by using sizeof(*lstat) to clear only the target entry.
