CVE-2026-45880

In the Linux kernel, the following vulnerability has been resolved: PCI/P2PDMA: Release per-CPU pgmap ref when vm_insert_page() fails When vm_insert_page() fails in p2pmem_alloc_mmap(), p2pmem_alloc_mmap() doesn't invoke percpu_ref_put() to free the per-CPU ref of pgmap acquired after gen_pool_alloc_owner(), and memunmap_pages() will hang forever when trying to remove the PCI device. Fix it by adding the missed percpu_ref_put().
