Scope: Unchanged
Confidentiality: None
Integrity: None
Availability: High

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

Attack Vector: Adjacent: The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
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 11 Feb 2026
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.

What to do

Upgrade iOS and iPadOS to 26.2 or 18.7.5; macOS to 26.2, 15.7.4 or 14.8.4; tvOS and visionOS and watchOS to 26.2.

AI-suggested

To mitigate CVE-2025-46303, organizations should prioritize deploying the official Apple patches: iOS 18.7.5, iPadOS 18.7.5, and corresponding updates for other Apple platforms. Beyond patching, organizations should implement strict policies controlling the use of external HID devices, including USB keyboards, mice, and other peripherals, especially in sensitive or high-security environments. Employ device management solutions to whitelist approved peripherals and block unknown or untrusted devices. Educate users about the risks of connecting unverified HID devices and encourage vigilance regarding physical device security. Network segmentation and endpoint protection can help detect anomalous device connections or behavior. Monitoring logs for unusual process crashes may provide early indicators of attempted exploitation. For high-security deployments, consider disabling or restricting HID interfaces where feasible. Regularly review and update security policies to incorporate lessons learned from this vulnerability.

Description

The issue was addressed with improved bounds checks. This issue is fixed in iOS 18.7.5 and iPadOS 18.7.5, iOS 26.2 and iPadOS 26.2, macOS Sequoia 15.7.4, macOS Sonoma 14.8.4, macOS Tahoe 26.2, tvOS 26.2, visionOS 26.2, watchOS 26.2. A malicious HID device may cause an unexpected process crash.

Impact

The primary impact of CVE-2025-46303 is on the availability of processes on Apple iOS and iPadOS devices. A malicious HID device can cause targeted processes to crash unexpectedly, potentially disrupting user workflows or critical applications. While confidentiality and integrity are not directly compromised, repeated or targeted exploitation could lead to denial-of-service conditions, affecting business continuity and user experience. Organizations relying heavily on Apple mobile devices for operational or strategic purposes may face interruptions. The requirement for user interaction limits remote exploitation but does not eliminate risk in environments where untrusted peripherals may be connected. This vulnerability could be leveraged in targeted attacks or by malicious insiders to disrupt device functionality. The absence of known exploits in the wild reduces immediate risk but does not preclude future exploitation once the vulnerability details are widely known.

CWE-119Improper Restriction of Operations within the Bounds of a Memory Buffer (opens in a new tab)
Class weaknessLikelihood of exploit: High
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Operation · Build and Compilation · Environment Hardening
Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index…
