- Summary
- gpiolib: acpi: initialize acpi_gpio_info struct
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
gpiolib: acpi: initialize acpigpioinfo struct
Since commit 7c010d463372 ("gpiolib: acpi: Make sure we fill struct acpigpioinfo"), uninitialized acpigpioinfo struct are passed to _acpifindgpio() and later in the call stack info->quirks is used in acpipopulategpiolookup. This breaks the i2chidcpi driver:
[ 58.122916] i2chidacpi i2c-UNIW0001:00: HID over i2c has not been provided an Int IRQ [ 58.123097] i2chidacpi i2c-UNIW0001:00: probe with driver i2chidacpi failed with error -22
Fix this by initializing the acpigpioinfo pass to __acpifindgpio()
