How to fix?

Upgrade SLES:15.7 kernel-source-azure to version 6.4.0-150700.20.11.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source-azure package and not the kernel-source-azure package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

regulator: gpio: Fix the out-of-bounds access to drvdata::gpiods

drvdata::gpiods is supposed to hold an array of 'gpio_desc' pointers. But the memory is allocated for only one pointer. This will lead to out-of-bounds access later in the code if 'config::ngpios' is > 1. So fix the code to allocate enough memory to hold 'config::ngpios' of GPIO descriptors.

While at it, also move the check for memory allocation failure to be below the allocation to make it more readable.
