Confidentiality: High
Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 28 Oct 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2024-44302, organizations and users should immediately update all affected Apple devices to the patched versions: iOS 17.7.1 or later, iPadOS 17.7.1 or later, macOS Sequoia 15.1, Sonoma 14.7.1, Ventura 13.7.1 or later, tvOS 18.1, visionOS 2.1, and watchOS 11.1. Beyond patching, organizations should implement strict controls on document and content sources, restricting users from opening untrusted or unsolicited files that may contain malicious fonts. Deploy endpoint protection solutions capable of detecting suspicious font files or anomalous font processing behavior. Educate users about the risks of opening unknown attachments or links, emphasizing caution with documents from unverified sources. Employ application whitelisting and sandboxing to limit the ability of untrusted applications to process font files. Monitor device logs for unusual font processing errors or crashes that may indicate attempted exploitation. For high-security environments, consider disabling font formats or features not required for business operations if feasible. Maintain robust backup and incident response plans to quickly address any data leakage incidents. Regularly review and update security policies to incorporate emerging threats related to font parsing vulnerabilities.

Description

The issue was addressed with improved checks. This issue is fixed in iOS 17.7.1 and iPadOS 17.7.1, iOS 18.1 and iPadOS 18.1, macOS Sequoia 15.1, macOS Sonoma 14.7.1, macOS Ventura 13.7.1, tvOS 18.1, visionOS 2.1, watchOS 11.1. Processing a maliciously crafted font may result in the disclosure of process memory.

Impact

The primary impact of CVE-2024-44302 is the potential disclosure of sensitive information from process memory on affected Apple devices. This can lead to leakage of confidential data such as authentication tokens, encryption keys, personal user information, or other sensitive application data. While the vulnerability does not allow attackers to execute arbitrary code or disrupt system availability, the confidentiality breach can facilitate further attacks such as identity theft, unauthorized access, or espionage. Organizations relying heavily on Apple devices for communication, data storage, or critical operations may face increased risk of data leakage if users open malicious content containing crafted fonts. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk, especially in environments where users may be targeted with malicious documents or web content. The vulnerability affects a broad range of Apple platforms, increasing the attack surface for organizations with diverse Apple device deployments. Although no exploits are currently known in the wild, the medium severity rating and potential for sensitive data exposure warrant prompt remediation to prevent future exploitation.
