CVE-2022-26710

What it actually does

Use-after-free vulnerability in memory management during processing of web content that enables arbitrary code execution.

Why it matters to the business

Attackers can gain full control over affected systems through malicious web content, resulting in data theft, system compromise, and operational disruption across widely used platforms with high ecosystem prevalence.

How an attack unfolds

An attacker crafts malicious web content and delivers it to a target; when processed, the use-after-free condition is triggered allowing arbitrary code execution, potentially leveraged by threat actors in targeted campaigns.

How to fix it

Upgrade affected curl/curl (GIT) installations to the fixed commit 5ce164e0e9290c96eb7d502173426c0a135ec008. Apply vendor patches for iOS 15.5, iPadOS 15.5, macOS Monterey 12.4, tvOS 15.5, and watchOS 8.6 where applicable.

How to confirm the fix worked

Verify version or commit hash matches the fixed release; test with known malicious web content samples in a controlled environment to confirm the use-after-free no longer occurs.

Typical attack path

1. Craft malicious web content exploiting the use-after-free flaw
2. Deliver content via web browsing or network vectors
3. Trigger memory corruption during content processing
4. Achieve arbitrary code execution on the target system

How to detect it

Review web browser and curl-related process logs for crashes or unexpected memory behavior; inspect network traffic for suspicious web content patterns associated with the vulnerability.

What your security team should do

• Prioritize immediate upgrade of curl to the specified fixed commit
• Monitor EPSS and exploit maturity trends for any increase in risk
• Apply available patches to all listed Apple platforms without delay
• Review web content handling components for similar memory issues
