CVE-2025-31235 is a vulnerability identified in Apple iPadOS and related macOS versions, stemming from a double free error in the system's memory management. A double free occurs when a program attempts to free the same memory location twice, which can lead to undefined behavior including crashes or potential exploitation. In this case, the flaw allows a local application with limited privileges to trigger unexpected system termination, effectively causing a denial of service (DoS) condition. The vulnerability does not affect confidentiality or integrity, as it does not allow data leakage or unauthorized modification, but it impacts system availability by crashing the device. The CVSS 3.1 base score is 6.5 (medium severity), reflecting that exploitation requires local access (AV:L), low attack complexity (AC:L), privileges (PR:L), no user interaction (UI:N), and results in high impact on availability (A:H) with no impact on confidentiality or integrity. Apple has fixed this issue by improving memory management in iPadOS 17.7.7, macOS Sequoia 15.5, macOS Sonoma 14.7.6, and macOS Ventura 13.7.6. There are no known exploits in the wild at this time. The vulnerability is tracked under CWE-415 (Double Free).

The primary impact of CVE-2025-31235 is denial of service through unexpected system termination on affected Apple devices. For organizations, this can translate into disruption of operations, especially in environments relying heavily on iPads or Macs for critical workflows. Repeated crashes could lead to productivity loss, potential data loss if unsaved work is interrupted, and increased support costs. While the vulnerability does not allow data compromise or privilege escalation, the availability impact can be significant in sectors such as healthcare, education, and enterprise environments where Apple devices are integral. Attackers with local access could leverage this flaw to disrupt services or cause instability, potentially as part of a broader attack chain. The absence of known exploits reduces immediate risk, but the medium severity score and ease of triggering the issue warrant timely remediation.

To mitigate CVE-2025-31235, organizations should prioritize updating all affected Apple devices to the patched versions: iPadOS 17.7.7 and the specified macOS releases (Sequoia 15.5, Sonoma 14.7.6, Ventura 13.7.6). Beyond patching, organizations should enforce strict app installation policies to limit local app installation to trusted sources only, reducing the risk of malicious apps exploiting this vulnerability. Implementing mobile device management (MDM) solutions can help enforce update compliance and restrict app permissions. Monitoring device stability and crash logs can provide early indicators of exploitation attempts. Additionally, educating users about the risks of installing untrusted applications and maintaining regular backups will help mitigate operational impacts. Network segmentation and endpoint protection can further reduce the risk of local attackers gaining access to devices.
