Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the macsmc multi-function device (mfd) where the mutex in struct apple smc is not initialized within the apple smc probe() function. This lack of initialization can lead to occasional NULL pointer dereferences when apple smc read() is called from the probe() functions of sub-devices.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
