CVE-2022-22624

What it actually does

Use-after-free flaw in memory management when handling web content, enabling arbitrary code execution in the affected process.

Why it matters to the business

Potential remote compromise of user systems via crafted web content, risking data theft or malware deployment; low exploitation likelihood reduces immediate urgency despite high severity.

How an attack unfolds

An attacker delivers malicious web content that triggers the use-after-free condition during rendering, allowing control of freed memory to execute arbitrary code without user privileges beyond visiting the page.

How to fix it

Update affected products to the fixed versions: macOS Monterey 12.3, iOS 15.4, iPadOS 15.4, tvOS 15.4, Safari 15.4 or apply the nodejs/node commit 5e5927ec2e685399689e4fcfe630565b3101207f where applicable.

How to confirm the fix worked

Verify product versions against the listed fixed releases and confirm memory management improvements are present in the updated builds.

Typical attack path

1. Craft malicious web content exploiting the use-after-free
2. Host or deliver the content via web page or link
3. Victim processes the content in the vulnerable component
4. Attacker gains arbitrary code execution in the process

How to detect it

Review web browser or rendering engine logs for crashes or unexpected memory access patterns around the time of web content processing; no specific post-exploitation artifacts are widely published.

What your security team should do

• Apply updates to fixed versions immediately for internet-facing or high-exposure systems
• Monitor EPSS trend for any increase in exploitation likelihood
• Block untrusted web content sources as a temporary mitigation
