kernel: iommu/amd: Fix clone_alias() to use the original device's devid

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit AMD driver. The clonealias function incorrectly uses the device ID devid when handling alias devices. This can lead to the propagation of wrong or stale Device Table Entry DTE entries to alias devices, potentially...

CVE-2026-89453

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit driver for AMD. This vulnerability occurs when the system handles certain memory access errors, specifically Page Request PPR faults, without properly releasing a reference to a PCI device. This oversight causes a...
