From: Gary Guo <gary@garyguo.net> mainline inclusion from mainline-v7.3-rc1 commit 3c28376273e8f5f9a6cb68478e210cf1b356a86e category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/19365 CVE: CVE-2026-90421 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- pci_device_id is not guaranteed to live longer than probe due to presence of dynamic ID. All information apart from driver_data can be easily retrieved from pci_dev, so just store driver_data.
