CVE 설명
In the Linux kernel, the following vulnerability has been resolved:
iommu/amd: Fix undefined behavior in devid_write debugfs function
When for_each_pci_segment() loop completes without finding a matching
segment, the pci_seg pointer is not NULL but points to an invalid memory
location (the list head). Accessing pci_seg->id after the loop causes
undefined behavior.
Fix this by handling the successful case inside the loop and returning
-EINVAL after the loop if no matching segment is found.
