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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: None: The vulnerable system can be exploited without any interaction from any user.
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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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-2024-54494, organizations and users should promptly update all affected Apple devices to the patched OS versions: iOS 18.2, iPadOS 18.2 and 17.7.3, macOS Sequoia 15.2, Sonoma 14.7.2, Ventura 13.7.2, tvOS 18.2, visionOS 2.2, and watchOS 11.2. Beyond patching, organizations should implement strict device management policies to ensure timely deployment of updates across all Apple endpoints. Employing runtime protections such as memory integrity checks and monitoring for anomalous memory access patterns can help detect exploitation attempts. Network-level defenses should be configured to limit exposure of Apple devices to untrusted networks, reducing the attack surface. Security teams should monitor threat intelligence feeds for any emerging exploit code or attack campaigns targeting this vulnerability. Additionally, conducting regular security audits and penetration testing on Apple device fleets can help identify any residual risks. For high-security environments, consider restricting the use of vulnerable OS versions until fully patched and validated.

Description

A race condition was addressed with additional validation. This issue is fixed in iOS 18.2 and iPadOS 18.2, iPadOS 17.7.3, macOS Sequoia 15.2, macOS Sonoma 14.7.2, macOS Ventura 13.7.2, tvOS 18.2, visionOS 2.2, watchOS 11.2. An attacker may be able to create a read-only memory mapping that can be written to.

Impact

The primary impact of CVE-2024-54494 is on the integrity of affected Apple operating systems. An attacker exploiting this vulnerability could write to memory regions that should be read-only, potentially enabling code injection, privilege escalation, or bypassing security controls. This could lead to unauthorized modification of system or application data, undermining trust in the device's operation. Although confidentiality and availability are not directly impacted, the integrity breach could facilitate further attacks that compromise sensitive information or disrupt services. Organizations relying on Apple devices for critical operations, secure communications, or sensitive data processing could face increased risk of targeted attacks or malware persistence. The medium severity and high attack complexity suggest that exploitation requires sophisticated techniques, but the lack of required privileges or user interaction lowers the barrier for remote attackers. The absence of known exploits currently reduces immediate risk but does not preclude future exploitation attempts.

Class weaknessLikelihood of exploit: MediumOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
Architecture and Design
In languages that support it, use synchronization primitives. Only wrap these around critical code to minimize the impact on performance.
Architecture and Design
Use thread-safe capabilities such as the data access abstraction in Spring.
Architecture and Design
Minimize the usage of shared resources in order to remove as much complexity as possible from the control flow and to reduce the likelihood of unexpected conditions occurring.
