CVE-2026-80894

A flaw was found in the Linux kernel's iommufd component. During the replacement of a device's I/O Memory Management Unit IOMMU domain, a parameter mismatch occurs where the iommufdhwptreplacedevice function incorrectly uses a new hardware page table hwpt with the handle of the old domain. This...

CVE-2026-80817

A flaw was found in the Linux kernel's iommu/iommufd component. A local user could exploit a race condition during the processing of I/O address space IOAS areas. This vulnerability occurs when iommufdioaschangeprocess attempts to access an IOAS area before its pages are fully mapped, leading to ...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: iommufd: Do not cause an overflow during division for dirty tracking. If pgshift is 63, then BITSPERTYPEbitmap-bitmap pgsize will result in an overflow to 0, which can trigger a division by zero. In this case, the index should...

In the Linux kernel, the following vulnerability has been resolved: iommufd: Fix UAF in selftest IOPF reporting IOMMUFD selftest TRIGGERIOPF borrows an attach handle from group-pasidarray without synchronizing against PASID detach, then a concurrent iommureportdevicefault can dereference that...

SUSE CVE-2026-89446

In the Linux kernel, the following vulnerability has been resolved: iommufd: Release current IOAS on xastore failure iommufdtakealliovarwsem takes an object reference and the iovarwsem write lock before storing the IOAS in the temporary ioaslist xarray. If xastore fails, the current IOAS has not...

SUSE CVE-2026-89447

In the Linux kernel, the following vulnerability has been resolved: iommufd: Avoid locking internal accesses during unmap iommufdaccessnotifyunmap skips internal accesses because they do not have an external unmap callback to invoke. However, the current test calls iommufdlockobj before checking...

CVE-2026-89447

A flaw was found in the Linux kernel's iommufd subsystem. A local attacker could exploit a vulnerability where an object reference is leaked during the unmapping of internal accesses. This occurs because the iommufdaccessnotifyunmap function incorrectly locks an object before checking if the acce...

CVE-2026-89445

A flaw was found in the Linux kernel's iommufd selftest component. This Use-After-Free UAF vulnerability occurs when the TRIGGERIOPF function borrows an attach handle without proper synchronization during a PASID detach operation. A concurrent device fault report can then access memory that has...

CVE-2026-89446

A flaw was found in the Linux kernel's iommufd component. When the system attempts to store an Input/Output Address Space IOAS object and the storage operation fails, the IOAS object's associated resources, such as its write lock and object reference, are not properly released. This oversight can...
