CVE-2026-68324

A flaw was found in the Intel IOMMU Input/Output Memory Management Unit driver within the Linux kernel. The dmarlatencydisable function incorrectly calculates the size for a memory clear operation, leading to an out-of-bounds write. A local attacker could exploit this vulnerability to corrupt...

CVE-2026-68347

A flaw was found in the Linux kernel's AMD IOMMU Input/Output Memory Management Unit driver. This vulnerability is caused by an unsafe lock order during the allocation of graphics domains gdom and within the IOMMUDESTROY free path. This issue could lead to a system crash or a denial of service Do...

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...
