CVE-2025-37746: perf/dwc_pcie: fix duplicate pci_dev devices

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: 0.23% (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 0778c3e01a9f382a5bc444a5271e013406642501, 7f35b429802a8065aa61e2a3f567089649f4d98e, a71c6fc87b2b9905dc2e38887fe4122287216be9.

Low priority for now. Upgrade to Linux Linux 0778c3e01a9f382a5bc444a5271e013406642501, 7f35b429802a8065aa61e2a3f567089649f4d98e, a71c6fc87b2b9905dc2e38887fe4122287216be9 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: perf/dwc_pcie: fix duplicate pci_dev devices During platform_device_register, wrongly using struct device pci_dev as platform_data caused a kmemdup copy of pci_dev. Worse still, accessing the duplicated device leads to list corruption as its mutex content (e.g., list, magic) remains the same as the original.
