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-2026-89447

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

CVE-2026-89447 affects the Linux kernel iommufd subsystem. In iommufd_access_notify_unmap() , the code calls iommufd_lock_obj() before checking whether the access is internal. When the access is internal, the loop skips it via continue, bypassing the matching iommufd_put_object() call used by the...
