CRITICALCVE-2025-24201 is a critical-severity (CVSS 10) Out-of-bounds Write vulnerability. It is in CISA's Known Exploited Vulnerabilities catalog (added 2025-03-13) — treat it as actively exploited and patch now. No vendor fix is recorded yet; mitigation options are listed below.
Exploitation Status
Actively exploited in the wild
- Confirmed by CISA's Known Exploited Vulnerabilities catalog on 2025-03-13. Federal agencies were required to remediate by 2025-04-03.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Description
An out-of-bounds write issue was addressed with improved checks to prevent unauthorized actions. This issue is fixed in visionOS 2.3.2, iOS 18.3.2 and iPadOS 18.3.2, macOS Sequoia 15.3.2, Safari 18.3.1, watchOS 11.4, iPadOS 17.7.6, iOS 16.7.11 and iPadOS 16.7.11, iOS 15.8.4 and iPadOS 15.8.4. Maliciously crafted web content may be able to break out of Web Content sandbox. This is a supplementary fix for an attack that was blocked in iOS 17.2. (Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 17.2.).

Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2025-24201 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
This vulnerability is only a risk for servers which utilize a GUI for system administration. This vulnerability can only be exploited when specific packages are used with a graphical interface to process untrusted web content, via GNOME for example.
Systems which do not rely on a GUI for system administration (commonly referred to as "headless") should confirm that GNOME shell and WebKitGTK are not present on the system. WebKitGTK3 is no longer used and can therefore be uninstalled without consequence. WebKitGTK4 is used in Red Hat Enterprise Linux 7 by the following packages: evolution-data-server, glade, gnome-boxes, gnome-initial-setup, gnome-online-accounts, gnome-shell, shotwell, sushi and yelp. To mitigate this vulnerability, consider removing certain GNOME packages. Note that uninstalling these packages will break functionality in GNOME, however the server can still be used via the terminal interface.Source: Red Hat security advisory for CVE-2025-24201 (CC BY 4.0)
