Description

nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error

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

nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error

The nouveau_dmem_copy_one function ensures that the copy push command is

sent to the device firmware but does not track whether it was executed

successfully.

In the case of a copy error (e.g., firmware or hardware failure), the

copy push command will be sent via the firmware channel, and

nouveau_dmem_copy_one will likely report success, leading to the

migrate_to_ram function returning a dirty HIGH_USER page to the user.

This can result in a security vulnerability, as a HIGH_USER page that may

contain sensitive or corrupted data could be returned to the user.

To prevent this vulnerability, we allocate a zero page. Thus, in case of

an error, a non-dirty (zero) page will be returned to the user.

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 high, integrity high, availability low.

CVSS metrics in full

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

  • 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: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: Low — limited, and the attacker does not choose what is affected.
