## Overview

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

optee: ffa: Add NULL check in optee_ffa_lend_protmem

Sashiko (locally) reports a possible null dereference under memory
pressure due to the lack of validation of the allocated pointer.

Fix that by adding the missing check.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
