CVE-2026-98435
EDAC/altera: Use parent device for devres in altr_portb_setup()
Description
In the Linux kernel, the following vulnerability has been resolved: EDAC/altera: Use parent device for devres in altr_portb_setup() Anchor the devres group and the devm-managed IRQ requests in altr_portb_setup() to the actual parent device (device->edac->dev) instead of the embedded struct device inside the copied per-port altr_edac_device_dev. This keeps devres_open_group(), devm_request_irq(), devres_remove_group() and devres_release_group() all referring to the same long-lived device so the group and the resources allocated inside it are torn down together.
