CVE-2026-20695: An app may be able to determine kernel memory layout in Apple macOS
CVE-2026-20695 is an information disclosure vulnerability in Apple macOS where an application may be able to determine the kernel memory layout. This issue was addressed by Apple through improved memory management and is fixed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, and macOS Tahoe 26.4. The vulnerability has a CVSS score of 6.2, indicating a medium severity level. It does not require user interaction and can be exploited with low complexity but requires local access.
AI Analysis
Technical Summary
This vulnerability allows an application on macOS to disclose kernel memory layout information due to insufficient memory management protections. Apple fixed the issue in specific macOS releases by improving memory management to prevent such information disclosure. The CVSS vector indicates the attack requires local access (AV:L), no privileges (PR:N), no user interaction (UI:N), and impacts confidentiality (C:H) but not integrity or availability.
Potential Impact
An attacker with local access to a vulnerable macOS system could gain knowledge of the kernel memory layout, which may facilitate further attacks such as kernel exploitation. However, the vulnerability does not directly allow code execution or denial of service. No known exploits are reported in the wild.
Mitigation Recommendations
Apply the official patches provided by Apple by upgrading to macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, or macOS Tahoe 26.4. These updates include the fix through improved memory management. No additional mitigation is indicated by the vendor advisory.
