In the Linux kernel, the following vulnerability has been resolved: i2c: acpi: Unbind mux adapters before delete There is an issue with ACPI overlay table removal specifically related to I2C multiplexers. Consider an ACPI SSDT Overlay that defines a PCA9548 I2C mux on an existing I2C bus. When this table is loaded we see the creation of a device for the overall PCA9548 chip and 8 further devices - one i2c_adapter each for the mux channels. These are all bound to their ACPI equivalents via an eventual invocation of acpi_bind_one(). When we unload the SSDT overlay we run into the problem. The ACPI devices are deleted as normal via acpi_device_del_work_fn() and the acpi_device_del_list. However, the following warning and stack trace is output as the deletion does not go smoothly: ------------[ cut here ]------------ kernfs: can not remove 'physical_node', no directory WARNING: CPU: 1 PID: 11 at fs/kernfs/dir.c:1674 kernfs_remove_by_name_ns+0xb9/0xc0 Modules linked in: CPU: 1 PID: ...
