CVE-2024-42085: usb: dwc3: core: remove lock of otg mode during gadget suspend/resume to avoid deadlock

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 17e2956633ca560b95f1cbbb297cfc2adf650649, 5.15.162, 7026576e89094aa9a0062aa6d10cba18aa99944c; azl3 kernel 6.6.35.1-5 on Azure Linux 3.0 6.6.47.1-1; azl3 kernel 6.6.47.1-1 on Azure Linux 3.0 6.6.47.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 17e2956633ca560b95f1cbbb297cfc2adf650649, 5.15.162, 7026576e89094aa9a0062aa6d10cba18aa99944c; azl3 kernel 6.6.35.1-5 on Azure Linux 3.0 6.6.47.1-1; azl3 kernel 6.6.47.1-1 on Azure Linux 3.0 6.6.47.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: core: remove lock of otg mode during gadget suspend/resume to avoid deadlock When config CONFIG_USB_DWC3_DUAL_ROLE is selected, and trigger system to enter suspend status with below command: echo mem > /sys/power/state There will be a deadlock issue occurring. Detailed invoking path as below: dwc3_suspend_common() spin_lock_irqsave(&dwc->lock, flags); <-- 1st dwc3_gadget_suspend(dwc); dwc3_gadget_soft_disconnect(dwc); spin_lock_irqsave(&dwc->lock, flags); <-- 2nd This issue is exposed by commit c7ebd8149ee5 ("usb: dwc3: gadget: Fix NULL pointer dereference in dwc3_gadget_suspend") that removes the code of checking whether dwc->gadget_driver is NULL or not. It causes the following code is executed and deadlock occurs when trying to get the spinlock. In fact, the root cause is the commit 5265397f9442("usb: dwc3: Remove DWC3 locking during gadget suspend/resume") that forgot to remove the lock of otg mode. So, remove the redundant lock of otg mode during gadget suspend/resume.
