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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 2026-10-26.

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 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

Organizations should immediately apply the security updates released by Apple, including iOS 17.7.1, iPadOS 17.7.1, and corresponding patches for other affected Apple operating systems. Beyond patching, organizations should implement strict message filtering and scanning policies to detect and block suspicious or malformed messages before they reach end-user devices. User education is essential to reduce the risk of interacting with untrusted messages, emphasizing caution when opening messages from unknown sources. Deploying mobile device management (MDM) solutions can help enforce update compliance and monitor device health. Network-level protections such as intrusion detection systems (IDS) and anomaly detection can help identify attempts to exploit this vulnerability. Additionally, organizations should review and harden their messaging infrastructure to limit exposure to crafted messages. Regular vulnerability assessments and penetration testing focused on messaging components can help detect similar weaknesses proactively.

Description

The issue was addressed with improved bounds 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 message may lead to a denial-of-service.

Impact

The primary impact of CVE-2024-44297 is denial-of-service, which can cause affected Apple devices to crash or become unresponsive upon processing malicious messages. This can disrupt business operations, especially in environments relying heavily on iOS and iPadOS devices for communication and productivity. Service interruptions may affect individual users, enterprises, and critical infrastructure sectors using Apple mobile platforms. Although the vulnerability does not expose sensitive data or allow unauthorized code execution, the loss of availability can degrade user experience and operational continuity. Attackers could exploit this flaw to target specific users or organizations, potentially as part of broader disruption campaigns. The lack of required privileges lowers the barrier to exploitation, increasing the risk in scenarios where users interact with untrusted messages. Overall, the threat is significant for organizations with large Apple device deployments and those in sectors where device availability is critical.
