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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Nov 2025
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 2026-10-25.

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

To mitigate CVE-2025-43384, organizations and users should promptly apply the security updates released by Apple for iOS 18.7.2, iPadOS 18.7.2, and other affected OS versions. Beyond patching, organizations should implement strict controls on media file sources, including filtering and scanning media files before distribution or opening. Employ mobile device management (MDM) solutions to enforce update policies and restrict installation of untrusted applications or media. Educate users about the risks of opening media files from unknown or untrusted sources to reduce the likelihood of triggering the vulnerability. Monitor application logs and device behavior for signs of unexpected app crashes or memory corruption that could indicate exploitation attempts. For high-security environments, consider disabling automatic media processing features or sandboxing media handling components to limit potential damage. Maintain an incident response plan that includes steps for handling suspected exploitation of media processing vulnerabilities.

Description

An out-of-bounds access issue was addressed with improved bounds checking. This issue is fixed in iOS 18.7.2 and iPadOS 18.7.2, iOS 26.1 and iPadOS 26.1, macOS Sequoia 15.7.2, macOS Tahoe 26.1, tvOS 26.1, visionOS 26.1. Processing a maliciously crafted media file may lead to unexpected app termination or corrupt process memory.

Impact

The primary impact of CVE-2025-43384 is denial-of-service through unexpected app termination, which can disrupt user experience and potentially critical applications on iOS and iPadOS devices. Memory corruption could also lead to unpredictable behavior or crashes, possibly opening avenues for further exploitation such as privilege escalation or code execution if chained with other vulnerabilities, although no such exploits are currently known. Organizations relying heavily on Apple mobile devices for business operations, especially those processing untrusted media content, may face operational disruptions. The vulnerability could affect enterprise environments, government agencies, and individuals, particularly where media files are shared or downloaded from untrusted sources. The scope includes a wide range of Apple devices running the affected OS versions, making the potential impact broad. However, the requirement for user interaction and lack of direct confidentiality or integrity impact limits the severity to medium. Nonetheless, disruption of critical apps or services could have cascading effects in sensitive environments.
