CVE-2026-68324 in Linux
Résumé
par MITRE • 10/08/2026
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.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
