CVE-2026-68347

CVE-2026-68347 pertains to the Linux kernel’s amd iommu code. The vulnerability arises from IRQ-unsafe locking in gdom allocation and in the IOMMU destroy/free path, leading to lock-order conflicts when HARDIRQ-safe locks become HARDIRQ-unsafe. The documented fix switches the allocation path in g...

CVE-2026-68325

The Linux kernel AMD IOMMU path (ivrs_acpihid parser) is affected by CVE-2026-68325. The parser appends entries to a fixed four-element early_acpihid_map and, unlike the IOAPIC/HPET parsers, does not reject a fifth entry before increasing the map size. The patch adds a capacity check at the commo...
