Summary
The Linux kernel from 6.7 includes an accelerometer driver for kionix-kx022a devices that does not free its allocated sample memory when a regmap operation fails in kx022a_fifo_enable() during buffer enable. The error path also leaves hardware configuration and driver state flags unreverted, potentially leaving WMI interrupts and buffers enabled.

Description from the CNA
In the Linux kernel, the following vulnerability has been resolved: iio: accel: kionix-kx022a: Prevent memory leak and fix state The driver allocates memory for samples at buffer enable path. If regmap operation fails in the kx022a_fifo_enable() at the buffer enable path, the allocated memory is never freed. Furthermore, the state information and previous hardware configuration(s) aren't undone, potentially leaving WMI interrupts and buffers enabled, or driver state flags wrong. Free the memory and revert the hardware configuration and state flags on error path.
