HID: elan: Fix potential double free in elan_input_configured

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.29% (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 1af20714fedad238362571620be0bd690ded05b6, 24f9dfdaece9bd75bb8dbfdba83eddeefdf7dc47, 5291451851feeb66fd4bf0826710f482f3b1ab38.

Low priority for now. Upgrade to Linux Linux 1af20714fedad238362571620be0bd690ded05b6, 24f9dfdaece9bd75bb8dbfdba83eddeefdf7dc47, 5291451851feeb66fd4bf0826710f482f3b1ab38 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: HID: elan: Fix potential double free in elan_input_configured 'input' is a managed resource allocated with devm_input_allocate_device(), so there is no need to call input_free_device() explicitly or there will be a double free. According to the doc of devm_input_allocate_device(): * Managed input devices do not need to be explicitly unregistered or * freed as it will be done automatically when owner device unbinds from * its driver (or binding fails).
