Description

EDAC/qcom: Do not pass llcc_driv_data as edac_device_ctl_info's pvt_info

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

EDAC/qcom: Do not pass llcc_driv_data as edac_device_ctl_info's pvt_info

The memory for llcc_driv_data is allocated by the LLCC driver. But when

it is passed as the private driver info to the EDAC core, it will get freed

during the qcom_edac driver release. So when the qcom_edac driver gets probed

again, it will try to use the freed data leading to the use-after-free bug.

Hence, do not pass llcc_driv_data as pvt_info but rather reference it

using the platform_data pointer in the qcom_edac driver.

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 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:H/I:H/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: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.
