Description

A flaw was found in the Linux kernel's i2c-qcom-cci driver. This vulnerability occurs when the device unbinding or driver removal process is initiated on systems where only one I2C master is initialized, despite the Qualcomm CCI controller providing two. This can lead to a NULL pointer dereference, potentially causing a system crash or denial of service. A local attacker could exploit this by triggering the driver removal under specific conditions.
