Mô tả CVE
In the Linux kernel, the following vulnerability has been resolved:
iommu/intel: Fix out-of-bounds memset in dmar_latency_disable()
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.
