CVE-2022-48724

CVE-2022-48724 concerns a memory leak in the Linux kernel’s IOMMU VT-d path during intel_setup_irq_remapping. The description in multiple connected documents states that after commit e3beca48a45b, the tear-down path could leak memory when dmar_enable_qi() errors, and that free() of the function p...

CVE-2024-35957

CVE-2024-35957 is a vulnerability in the Linux kernel's Intel Virtualization Technology for Directed I/O VT-d subsystem. The issue stems from an incorrect assumption that each device has a unique source ID, leading to potential conflicts and system warnings during the IOMMU probe process. This fl...

CVE-2024-35957

The CVE-2024-35957 vuln in the Linux kernel/IOMMU VT-d path arises from probing code that tracked all probed devices in an rbtree by source ID, assuming uniqueness that VT-d does not guarantee. The fix, per the linked advisories, is to only track devices that have PCI ATS capabilities in the iomm...
