CVE-2022-48618
HIGHCVE-2022-48618 is a high-severity (CVSS 7) Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in apple ipados. It is in CISA's Known Exploited Vulnerabilities catalog (added 2024-01-31) — treat it as actively exploited and patch now. O3 Security detects and blocks CVE-2022-48618 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.
The issue was addressed with improved checks. This issue is fixed in macOS Ventura 13.1, watchOS 9.2, iOS 16.2 and iPadOS 16.2, tvOS 16.2. An attacker with arbitrary read and write…
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Description
The issue was addressed with improved checks. This issue is fixed in macOS Ventura 13.1, watchOS 9.2, iOS 16.2 and iPadOS 16.2, tvOS 16.2. An attacker with arbitrary read and write capability may be able to bypass Pointer Authentication. Apple is aware of a report that this issue may have been exploited against versions of iOS released before iOS 15.7.1.

Detection & mitigation playbook
Vendor / applianceDetect
Inventory every apple ipados deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Remediation status
No patch has shipped for CVE-2022-48618 yet — track the apple ipados advisory for a fixed release and apply the workarounds below in the meantime.
Mitigate without a patch
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2022-48618 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2022-48618. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-48618 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2022-48618 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
