CVE-2025-39960: gpiolib: acpi: initialize acpi_gpio_info struct

HighCVSS 7.8 · v3.1—No exploit Fix available

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: 0.15% (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 19c839a98c731169f06d32e7c9e00c78a0086ebe, 27d94a2a52cbb54927c0140bd5b978c56e9a283a.

Low priority for now. Upgrade to Linux Linux 19c839a98c731169f06d32e7c9e00c78a0086ebe, 27d94a2a52cbb54927c0140bd5b978c56e9a283a or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: gpiolib: acpi: initialize acpi_gpio_info struct Since commit 7c010d463372 ("gpiolib: acpi: Make sure we fill struct acpi_gpio_info"), uninitialized acpi_gpio_info struct are passed to __acpi_find_gpio() and later in the call stack info->quirks is used in acpi_populate_gpio_lookup. This breaks the i2c_hid_cpi driver: [ 58.122916] i2c_hid_acpi i2c-UNIW0001:00: HID over i2c has not been provided an Int IRQ [ 58.123097] i2c_hid_acpi i2c-UNIW0001:00: probe with driver i2c_hid_acpi failed with error -22 Fix this by initializing the acpi_gpio_info pass to __acpi_find_gpio()
