Availability: Low

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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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 15 Sep 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-2025-43349, organizations should promptly apply the official Apple security updates: iOS 18.7, iPadOS 18.7, macOS Sequoia 15.7, macOS Sonoma 14.8, macOS Tahoe 26, tvOS 26, visionOS 26, and watchOS 26. Until patches are deployed, users should avoid opening untrusted or unsolicited video files, especially from unknown sources. Implementing endpoint protection solutions that can detect and block malicious media files may provide additional defense. Organizations should educate users about the risks of opening suspicious video content and enforce policies restricting the use of unauthorized media files. Monitoring application crash logs and unusual app terminations can help identify potential exploitation attempts. For environments with high security requirements, consider restricting video file formats or sources to trusted channels only. Regularly review and update device management policies to ensure timely deployment of security patches across all Apple devices.

Description

An out-of-bounds write issue was addressed with improved input validation. This issue is fixed in iOS 18.7 and iPadOS 18.7, iOS 26 and iPadOS 26, macOS Sequoia 15.7, macOS Sonoma 14.8, macOS Tahoe 26, tvOS 26, visionOS 26, watchOS 26. Processing a maliciously crafted video file may lead to unexpected app termination.

Impact

The primary impact of CVE-2025-43349 is availability degradation through denial-of-service conditions caused by application crashes when processing maliciously crafted video files. This can disrupt user experience and potentially impact business operations relying on affected Apple devices for media consumption or processing. Since the vulnerability requires local access and user interaction, remote exploitation is not feasible, limiting the attack surface. However, targeted attacks or social engineering could induce users to open malicious videos, causing app instability or crashes. There is no impact on confidentiality or integrity, and no privilege escalation or code execution is possible. Organizations with large deployments of Apple devices, especially in environments where video files are frequently shared or processed, may face operational disruptions if unpatched. The lack of known exploits reduces immediate risk but patching remains critical to prevent future exploitation attempts.
