## Overview

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

crypto: sa2ul - stop probe if context pool creation fails

sa_ul_probe() calls sa_init_mem() to create the DMA pool used for
security context buffers, but ignores its return value. If pool creation
fails, probe still continues with DMA setup, algorithm registration and
child population even though later request setup depends on that pool.

Stop probing when sa_init_mem() fails, and route that failure to the PM
cleanup path without attempting to destroy an uncreated DMA pool.

## Remediation

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