What action is associated with a software patch?

A software patch is specifically designed to solve problems in the code, addressing issues such as bugs, vulnerabilities, or performance hitches. Patches are critical in cybersecurity as they often fix security vulnerabilities that could be exploited by malicious actors. This process helps ensure that the software runs more smoothly and securely.

While adding new features is often part of a full software update or upgrade, patches primarily focus on existing issues rather than introducing new capabilities. Similarly, while upgrading security protocols is essential, specific improvements to security typically occur through patches aimed at fixing vulnerabilities rather than on completely changing the structure or protocols themselves. The creation of a user manual is unrelated to the purpose of a software patch and instead deals with user guidance and support documentation. Thus, the distinct role of a patch in rectifying issues makes it the correct answer.
