"value": "In the Linux kernel, the following vulnerability has been resolved:\n\niommu/intel: Fix out-of-bounds memset in dmar_latency_disable()\n\ndmar_latency_disable() intends to zero out only the single\nlatency_statistic entry for the given type, but the memset size was\ncomputed as sizeof(*lstat) * DMAR_LATENCY_NUM, which clears the entire\narray starting from &lstat[type].\n\nWhen type > 0, this writes beyond the end of the allocated array,\ncorrupting adjacent memory.\n\nFix by using sizeof(*lstat) to clear only the target entry."
