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.

Can you explain this vulnerability to me?

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.


How can this vulnerability impact me? :

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.
