Summary

Linux kernel versions from 4.9 are affected. In the EDAC Altera driver's altr_portb_setup() function, the devres group and devm-managed IRQ requests are anchored to an embedded struct device inside a copied per-port structure instead of the parent device, so the group and its resources are not torn down together.

Description from the CNA

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.
