In the Linux kernel, the following vulnerability has been resolved: nvmet: use the local P2P device on metadata allocation failure nvmet_req_alloc_p2pmem_sgls() assigns req->p2p_dev only after the data and metadata SGL allocations succeed. If the data allocation succeeds but the metadata allocation fails, out_free_sg passes req->p2p_dev to pci_p2pmem_free_sgl() before that assignment has taken place. Pass the local p2p_dev argument instead, so cleanup uses the same PCI device as the successful data allocation.

Are you affected?

Enter the version you run. The result uses only the ranges stored on this record.

The check returns affected, not affected, or incomplete. It does not guess a version that is missing from the record.
