Description
In the Linux kernel, the following vulnerability has been resolved: regulator: da9063: fix null pointer deref with partial DT config When some of the da9063 regulators do not have corresponding DT nodes a null pointer dereference occurs on boot because such regulators have no init_data causing the pointers calculated in da9063_check_xvp_constraints() to be invalid. Do not dereference them in this case.

Executive Summary

This vulnerability occurs in the Linux kernel's da9063 regulator driver. When some da9063 regulators lack corresponding Device Tree (DT) nodes, a null pointer dereference happens during boot because these regulators have no initialization data (init_data). This causes invalid pointers in the function da9063_check_xvp_constraints(), leading to a null pointer dereference. The fix prevents dereferencing these pointers when init_data is missing.

Impact Analysis

The vulnerability can cause a null pointer dereference during system boot, which may lead to a kernel crash or system instability. This can result in denial of service or prevent the system from booting properly if affected hardware is present.
