Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
[REJECTED CVE] A vulnerability was identified in the Linux kernel’s powerpc/pseries/iommu subsystem, where dynamically adding a PCI device during Dynamic Logical Partitioning (DLPAR) could trigger a NULL pointer dereference, leading to a kernel oops. This occurred due to the missing initialization of the iommu_device structure in newly allocated pci_controller instances, unlike during system boot where iommu_device_register() is properly invoked. An attacker with the ability to repeatedly add and remove PCI devices could exploit this flaw to trigger system crashes, potentially causing a denial-of-service (DoS) condition
