A vulnerability in the Linux kernel's iommu/vt-d subsystem could cause a NULL pointer dereference or refcount corruption. This occurs when teardown operations are executed unconditionally despite a NULL dev_pasid pointer, potentially leading to use-after-free conditions. The issue has been fixed by adding an early return if dev_pasid is NULL before teardown. This vulnerability affects multiple Linux kernel versions prior to 7.0.0-28.28 and related builds. A patch is available and should be applied to mitigate the risk. Join the discussion | GCVE Database | 06/26/2026, 20:17:00 UTC Added: 07/17/2026, 10:15:45 UTC |
