Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a race condition during the initialization of the pmic glink child drivers in the Linux kernel. As pointed out by Stephen Boyd, the protection-domain notifiers may fire and schedule associated work before the client registration returns, resulting in a NULL pointer dereference as the
client pointer is blindly dereferenced. This occurs when the protection domain registry is populated at the time of registration, which became more likely with the introduction of the commit '1ebcde047c54 ("soc: qcom: add pd-mapper implementation")'. The vulnerable code is identical across the altmode, battery manager, and usci child drivers.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
