Memory corruption in Apple CoreMedia video file processing

IdentifiersCVE-2025-24211CWE-119

CVE-2025-24211 is a memory-handling vulnerability in Apple CoreMedia affecting Apple platforms including visionOS, iOS, iPadOS, macOS, and tvOS. According to Apple, processing a maliciously crafted video file may lead to unexpected application termination or corruption of process memory. The issue was addressed through improved memory handling and is fixed in visionOS 2.4, macOS Ventura 13.7.5, macOS Sonoma 14.7.5, macOS Sequoia 15.4, tvOS 18.4, iPadOS 17.7.6, iOS 18.4, and iPadOS 18.4. Based on the available information, the flaw is triggered during parsing or handling of crafted video content in CoreMedia, but Apple has not publicly disclosed the specific vulnerable function or root-cause primitive beyond the memory-handling characterization.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can cause the target application or process handling the video to terminate unexpectedly, resulting in denial of service. Because Apple states that process memory may be corrupted, the vulnerability also carries the potential for more serious consequences depending on exploitability in the affected context, including destabilization of the process and possibly further control over execution, but the provided information does not confirm arbitrary code execution for this specific CVE.

Mitigation

If you can’t patch tonight, do this now.

Until patches can be applied, reduce exposure by avoiding the opening, previewing, or automated processing of untrusted video files, especially from untrusted senders or external sources. Limit workflows and applications that automatically ingest or render externally supplied media, and use platform controls that restrict delivery of untrusted content where possible. These are only partial mitigations; vendor updates are the primary mitigation.

Remediation

Patch, then assume compromise.

Apply the vendor fixes provided by Apple. The issue is fixed in visionOS 2.4, tvOS 18.4, iOS 18.4, iPadOS 18.4, iPadOS 17.7.6, macOS Ventura 13.7.5, macOS Sonoma 14.7.5, and macOS Sequoia 15.4. Systems running affected earlier versions should be updated to the corresponding patched release as soon as operationally feasible.
