CVE-2026-97967: hwmon: (corsair-cpro) Remove debugfs entries when probe fails

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 4ee875c423c66c45d7ef7bbff403cd0e3971e0a2, a5de53b08cc319dadce6fb68d33749ea37962952, ae01aafd8214e48cb7eff11e92dfbf3778d52d9d.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 4ee875c423c66c45d7ef7bbff403cd0e3971e0a2, a5de53b08cc319dadce6fb68d33749ea37962952, ae01aafd8214e48cb7eff11e92dfbf3778d52d9d or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: hwmon: (corsair-cpro) Remove debugfs entries when probe fails ccp_debugfs_init() registers debugfs files whose private data is the devm allocated ccp. If hwmon_device_register_with_info() fails right after it, ccp_probe() returns without removing them: the HID core then frees ccp, and ccp_remove() is not called for a failed probe, so the files stay behind. Reading one of them dereferences the freed pointer. Remove the debugfs entries on that error path. debugfs_remove_recursive() waits for readers already inside the show callbacks, so ccp is no longer reachable through debugfs by the time probe returns.
