CVE-2026-74713

A flaw was found in the Linux kernel's vhostiotlb module. Non-retiring tables within this module can continue to allocate entries even after reaching their configured limits. This allows a local attacker or a malicious guest operating system to trigger a continuous stream of IOTLB updates, leadin...

CVE-2026-74573

Concise summary: CVE-2026-74573 affects the Linux kernel IOMMU arm-smmu-v3-iommufd. The vulnerability arises when a vDEVICE is mapped to more than one stream: arm_vsmmu_vsid_to_sid() uses only master->streams[0], so guests with multiple streams may not invalidate all ATC/IOTLB entries; if ther...
