Description

usb: cdns3: Put the cdns set active part outside the spin lock

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

usb: cdns3: Put the cdns set active part outside the spin lock

The device may be scheduled during the resume process,

so this cannot appear in atomic operations. Since

pm_runtime_set_active will resume suppliers, put set

active outside the spin lock, which is only used to

protect the struct cdns data structure, otherwise the

kernel will report the following warning:

BUG: sleeping function called from invalid context at drivers/base/power/runtime.c:1163

in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 651, name: sh

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.
