Description
In the Linux kernel, the following vulnerability has been resolved: hwmon: (pmbus/core) increase number of phases and add new mask Increase the number of phases to 16 as a new upcoming device supports such a number. While at it, add a new mask for controlling the source of the output voltage. Note (groeck): This patch was meant to prepare for support of MAX20826 and compatible devices, which support more than 10 phases per page. However, Sashiko reports that the mp2975 driver already supports up to 14 phases, and the mp2856 driver supports up to 12 phases. This already has the potential for out-of-bounds writes when probing the affected chips, making this patch a bug fix.
