## Overview

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

soc: ti: ti_sci_pm_domains: Check for null return of devm_kcalloc

The allocation funciton devm_kcalloc may fail and return a null pointer,
which would cause a null-pointer dereference later.
It might be better to check it and directly return -ENOMEM just like the
usage of devm_kcalloc in previous code.

## Affected

- `linux_kernel < 5.10.121`
- `linux_kernel >= 5.11, < 5.15.46`
- `linux_kernel >= 5.16, < 5.17.14`
- `linux_kernel >= 5.18, < 5.18.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.18.3`
