Description

In the Linux kernel, the following vulnerability has been resolved: regulator: da9063: better fix null deref with partial DT Two versions of the original patch were sent but V1 was merged instead of V2 due to a mistake. So update to V2. The advantage of V2 is that it completely avoids dereferencing the pointer, even just to take the address, which may fix problems with some compilers. Both versions work on my gcc 9.4 but use the safer one.

Affected products

Linux kernel: from 6.4.7 before 6.4.12; 6.5-rc3, 6.5-rc4, 6.5-rc5, 6.5-rc6 — fixed in 6.4.12

How to fix

Upgrade to a fixed version: Linux kernel 6.4.12. Check the vendor advisory for mitigations.
