Description

PCI: imx6: Fix suspend/resume support on i.MX6QDL

In the Linux kernel, the following vulnerability has been resolved:

PCI: imx6: Fix suspend/resume support on i.MX6QDL

The suspend/resume functionality is currently broken on the i.MX6QDL

platform, as documented in the NXP errata (ERR005723):

https://www.nxp.com/docs/en/errata/IMX6DQCE.pdf

This patch addresses the issue by sharing most of the suspend/resume

sequences used by other i.MX devices, while avoiding modifications to

critical registers that disrupt the PCIe functionality. It targets the

same problem as the following downstream commit:

https://github.com/nxp-imx/linux-imx/commit/4e92355e1f79d225ea842511fcfd42b343b32995

Unlike the downstream commit, this patch also resets the connected PCIe

device if possible. Without this reset, certain drivers, such as ath10k

or iwlwifi, will crash on resume. The device reset is also done by the

driver on other i.MX platforms, making this patch consistent with

existing practices.

Upon resuming, the kernel will hang and display an error. Here's an

example of the error encountered with the ath10k driver:

ath10k_pci 0000:01:00.0: Unable to change power state from D3hot to D0, device inaccessible

Unhandled fault: imprecise external abort (0x1406) at 0x0106f944

Without this patch, suspend/resume will fail on i.MX6QDL devices if a

PCIe device is connected.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: None.
  • Integrity impact: None.
  • Availability impact: High — total loss, or loss the attacker controls.
