Patch

A software update that corrects errors or fixes security vulnerabilities.

A software update that fixes a problem, such as a security vulnerability.

Developers can then release patches, which are updates that fix problems. Installing security updates for the operating system and applications closes known weaknesses that attackers might otherwise use to install malware. These updates repair the software being protected; anti-malware updates improve the protection software's ability to recognise threats.

A software change released to fix a problem, such as a security vulnerability.

For an explanation, link the weakness to the attack: missing patches leave security flaws available for exploitation; outdated malware definitions may prevent new malware being recognised.

A software update that corrects errors or security vulnerabilities.

A patch is an update that corrects errors or security vulnerabilities. If a patch is available but has not been applied, the software remains unpatched: the weakness is still present and an attacker may exploit it to access confidential data or install malware.
