Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： EDAC/altera：在 altr_portb_setup() 中使用父设备来管理 devres 在 altr_portb_setup() 函数中，将 devres 资源组以及由 devm 管理的 IRQ 请求锚定到实际的父设备（即 device->edac->dev），而不是锚定到被复制的每个端口对应的 embedded struct device（altr_edac_device_dev 内部）。 此举确保 devres_open_group()、devm_req

Vulnerability Title
EDAC/altera: Use parent device for devres in altr_portb_setup()
Source: CVE Program / CVE List V5
Vulnerability 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.
