Out-of-Bounds Access Vulnerability in Apple Operating Systems

CVE-2025-43346

What is CVE-2025-43346?

CVE-2025-43346 is an out-of-bounds access vulnerability identified in various Apple operating systems, including tvOS, watchOS, iOS, iPadOS, visionOS, and macOS. This vulnerability arises from inadequate bounds checking when processing media files, potentially allowing a maliciously crafted file to cause unpredictable behavior. Specifically, it can lead to unexpected application termination or the corruption of process memory, significantly increasing the risk of system instability or application crashes. Given the widespread deployment of these operating systems across Apple devices, this flaw poses a serious threat to organizations that rely on these platforms for critical operations.

Potential impact of CVE-2025-43346

1. Application Crashes: The vulnerability can cause applications to terminate unexpectedly, which may disrupt user operations and decrease overall productivity. Essential applications that organizations depend on could be rendered unusable until a fix is applied.

2. Data Corruption: Corrupting process memory can lead to the loss of data or unintended modifications of the application's state, potentially resulting in severe data integrity issues that affect business continuity and decision-making processes.

3. Increased Attack Surface: As this vulnerability allows an attacker to manipulate application behavior through malicious media files, it could serve as a vector for more sophisticated attacks, potentially leading to unauthorized system access or additional vulnerabilities being exploited.
