In the Linux kernel, the following vulnerability has been resolved:

i2c: qcom-cci: Fix NULL pointer dereference in cci_remove()

On all modern platforms Qualcomm CCI controller provides two I2C masters, and on particular boards only one I2C master may be initialized, and in such cases the device unbinding or driver removal causes a NULL pointer dereference, because cci_halt() is called for all two I2C masters, but a completion is initialized only for the single enabled master:
