In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Avoid NULL pointer dereference or refcount corruption Commit… (CVE-2026-53281)CVE-2026-53281 0 A vulnerability in the Linux kernel's iommu/vt-d component could lead to a NULL pointer dereference or refcount corruption. This occurs when a device PASID is not found, causing teardown operations to execute unconditionally on a NULL pointer, potentially resulting in use-after-free conditions for devices sharing the domain. The issue has been fixed by adding an early return if the device PASID is NULL before teardown. Red Hat has released security updates for Red Hat Enterprise Linux 9 and 10 to address this vulnerability. Systems must be rebooted after applying the update.
