CVE-2026-90242

A flaw was found in the Linux kernel's iommu/vt-d subsystem. When an IOMMU Input/Output Memory Management Unit domain with an iopfhandler is replaced by another domain at the Requestor ID RID level, a reference count for the old domain is not properly released. This resource leak prevents the...

CVE-2026-90243

A flaw was found in the Linux kernel's IOMMU/VT-d subsystem. During the tear-down of copied context entries, the kernel zeroes out parts of an entry before clearing its "Present" bit and invalidating related caches. This timing issue allows hardware to fetch a partially cleared entry that is stil...

CVE-2026-90241

A flaw was found in the Linux kernel's iommu/vt-d subsystem. During the setup of scalable-mode context entries for PCI devices, an error can occur that leaves behind invalid context entries. These entries may point to memory that has already been freed. An attacker could potentially exploit this ...

CVE-2026-90240

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit / VT-d Virtualization Technology for Directed I/O component. When tearing down Direct Memory Access DMA aliases of a device, the system fails to flush the context cache with the correct Source ID SID. This oversight...
