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

drm/amdgpu: fix calltrace warning in amddrm_buddy_fini

The following call trace is observed when removing the amdgpu driver, which

is caused by that BOs allocated for psp are not freed until removing.

[61811.450562] RIP: 0010:amddrm_buddy_fini.cold+0x29/0x47 [amddrm_buddy]

For smu v13_0_2, if the GPU supports xgmi, refer to

commit f5c7e7797060 ("drm/amdgpu: Adjust removal control flow for smu v13_0_2"),

it will run gpu recover in AMDGPU_RESET_FOR_DEVICE_REMOVE mode when removing,

which makes all devices in hive list have hw reset but no resume except the

basic ip blocks, then other ip blocks will not call .hw_fini according to

ip_block.status.hw.

Since psp_free_shared_bufs just includes some software operations, so move

it to psp_sw_fini.

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.
