In the Linux kernel, the following vulnerability has been resolved:
PCI: endpoint: pci-epf-vntb: Stop cmd_handler work in epf_ntb_epc_cleanup
Disable the delayed work before clearing BAR mappings and doorbells to
avoid running the handler after resources have been torn down.
Unable to handle kernel paging request at virtual address ffff800083f46004
[...]
