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).

Detectable: no evidence on record.

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

Apple has released an official fix for this vulnerability in macOS Sonoma 14.4. Users and administrators should apply this update to remediate the issue. No additional mitigation steps are indicated by the vendor advisory.

Description

CVE-2024-23248 is a vulnerability in Apple macOS Sonoma where processing a specially crafted file may lead to a denial-of-service condition or potentially disclose memory contents. The issue is related to improper memory handling. Apple addressed this vulnerability in macOS Sonoma 14.4 by improving memory handling to prevent these impacts. The vulnerability has a CVSS score of 6.5, indicating a medium severity level. There are no known exploits in the wild at the time of this advisory. The vendor advisory confirms the availability of an official fix in macOS Sonoma 14.4.

Impact

The vulnerability can cause denial-of-service or potential disclosure of memory contents when a file is processed on affected macOS Sonoma systems. This could disrupt application availability or leak sensitive memory data. There are no reports of active exploitation. The impact is limited to availability and potential information disclosure, with no integrity or privilege escalation effects noted.

Summary

CVE-2024-23248 affects Apple macOS Sonoma and involves a memory handling flaw that can be triggered by processing a file. This flaw may cause the application to terminate unexpectedly (denial-of-service) or potentially allow disclosure of memory contents. Apple fixed this vulnerability by improving memory handling in the macOS Sonoma 14.4 update. The CVSS 3.1 base score is 6.5, with attack vector network, low attack complexity, no privileges required, user interaction required, scope unchanged, and impact limited to availability (denial-of-service) but no confidentiality or integrity impact.

CWE-404Improper Resource Shutdown or Release (opens in a new tab)
Class weaknessLikelihood of exploit: Medium
The product does not release or incorrectly releases a resource before it is made available for re-use.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation
It is good practice to be responsible for freeing all resources you allocate and to be consistent with how and where you free memory in a function. If you allocate memory that you intend to free upon completion of the function, you must be sure to free the memory at all exit points for that function including error…
Implementation
Memory should be allocated/freed using matching functions such as malloc/free, new/delete, and new[]/delete[].
