Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Original source description

Read the full publisher description

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.
