CVE-2026-53283

A flaw was found in the Linux kernel's AMD IOMMU Input/Output Memory Management Unit driver. A local attacker or a specially configured PCI device could trigger an out-of-bounds read in the rlookupamdiommu function. This vulnerability occurs when a PCI device's Bus Device Function BDF is not...

CVE-2026-53283

CVE-2026-53283 covers a bounds-check failure in the Linux kernel AMD IOMMU path. The issue arises in __rlookup_amd_iommu(): rlookup_table[devid] is indexed without an internal bounds check, and iommu_device_register() iterates all PCI devices, calling amd_iommu_probe_device() for each. If a devic...

CVE-2026-53053

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-2026-53053 iommu/amd: Fix clone_alias() to use the original device's devid

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Fix clonealias to use the original device's devid Currently clonealias assumes first argument pdev is always the original device pointer. This function is called by pciforeachdmaalias which based on topology decides to...
