Description

drm/mediatek: dp: Change logging to dev for mtk_dp_aux_transfer()

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

drm/mediatek: dp: Change logging to dev for mtk_dp_aux_transfer()

Change logging from drm_{err,info}() to dev_{err,info}() in functions

mtk_dp_aux_transfer() and mtk_dp_aux_do_transfer(): this will be

essential to avoid getting NULL pointer kernel panics if any kind

of error happens during AUX transfers happening before the bridge

is attached.

This may potentially start happening in a later commit implementing

aux-bus support, as AUX transfers will be triggered from the panel

driver (for EDID) before the mtk-dp bridge gets attached, and it's

done in preparation for the same.

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.
