Short explanation
An issue has been resolved in the Linux kernel EDAC/altera subsystem within altr_portb_setup(), anchoring devres group and IRQ requests to the parent device [S0].
Failure to anchor resources to the correct long-lived device can lead to instability in resource and memory management [S0].
What should be done?
- Follow vendor advisories [S0]
Chain of evidence and sources
altr_portb_setup() fonksiyonunda devres grup ve IRQ istekleri üst cihaza bağlanmıştır.
Devres fonksiyonlarının aynı uzun ömürlü cihaza referans vermesi sağlanmıştır.
Show the technical text from the sources
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.
