Patch management fixes known software flaws before attackers exploit them, reducing intrusion risk; prioritize critical systems and verify deployment.

Background for this topic.
Patch is a software, firmware, or configuration update that fixes a defect, including a vulnerability an attacker could use to gain access, execute code, escalate privileges, or expose data. Patching reduces the exploitable attack surface across operating systems, applications, network devices, and embedded systems; it does not remove risk from unsupported or misconfigured assets, and updates can sometimes introduce compatibility or availability problems.
Effective patch management starts with an accurate inventory and vulnerability assessment, then prioritizes internet-facing systems, high-impact assets, and flaws known to be exploited. Organizations should test updates where practical, deploy them within defined time limits, verify installation, and retain rollback or compensating controls when immediate patching is unsafe. Monitoring vendor advisories and threat intelligence can identify urgent fixes, while documenting exceptions and coverage supports vulnerability management and audit requirements.
Google on Friday shipped emergency fixes to address a security vulnerability in the Chrome web browser that it said is being actively exploited in the wild
Google has released Chrome 105.0.5195.102 for Windows, Mac, and Linux users to address a high-severity zero-day security flaw exploited by attackers in attacks, the sixth Chrome zero-day patched this year. [...]
The flaw would allow the processing of maliciously crafted web content and arbitrary code execution
Apple continues a staged update process to address a WebKit vulnerability that allows attackers to craft malicious web content to load malware on affected devices.
Microsoft on Wednesday disclosed details of a now-patched "high severity vulnerability" in the TikTok app for Android that could let attackers take over accounts when victims clicked on a malicious link
Apple has released new security updates to backport patches released earlier this month to older iPhones and iPads addressing a remotely exploitable WebKit zero-day that allows attackers to execute arbitrary code on unpatched devices. [...]
Patch as soon as you can - that recent WebKit zero-day affecting new iPhones is apparently being used against older models, too.
24 existing bugs fixed. And, we hope, numerous potential future bugs prevented.
