Lifecycle Timeline
4DescriptionCVE.org
An information disclosure issue was addressed with improved memory management. This issue is fixed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4. An app may be able to determine kernel memory layout.
AnalysisAI
An information disclosure vulnerability in macOS allows applications to determine kernel memory layout through improper memory management, enabling potential attacks that rely on kernel address space layout randomization (KASLR) bypass. This issue affects macOS Sequoia (before 15.7.5), macOS Sonoma (before 14.8.5), and macOS Tahoe (before 26.4). An unprivileged application can exploit this to leak kernel memory addresses, which is a critical prerequisite for more sophisticated kernel exploitation attacks. No CVSS score, EPSS probability, or evidence of active exploitation in CISA KEV catalog has been published, though the vulnerability was patched by Apple across three major OS versions, suggesting it was discovered through responsible disclosure rather than in-the-wild exploitation.
Technical ContextAI
This vulnerability resides in macOS kernel memory management subsystems and relates to information disclosure through side-channel or direct memory access patterns. The CVE references identify affected macOS versions across multiple release branches (Sequoia 15.7.5, Sonoma 14.8.5, and Tahoe 26.4) as documented in Apple security updates (support.apple.com/en-us/126794, 126795, 126796). While a specific CWE was not assigned in the CVE record, the vulnerability mechanism of 'determining kernel memory layout' aligns with CWE-200 (Information Exposure) and potentially CWE-208 (Observable Timing Discrepancy) or similar side-channel weaknesses. The root cause appears to be inadequate isolation or randomization of kernel memory addresses accessible to user-space applications, which is fundamental to KASLR defense mechanisms on modern operating systems.
RemediationAI
Update macOS Sequoia to version 15.7.5 or later, macOS Sonoma to version 14.8.5 or later, or macOS Tahoe to version 26.4 or later, depending on which release branch is in use. Security updates are available through System Preferences > General > Software Update on affected systems. Organizations should prioritize deployment of these patches within their standard macOS update windows, as they address a kernel-level information disclosure that could enable subsequent kernel exploitation attacks. No workarounds are available for this vulnerability; patching is the only remediation path. Verify patch application by confirming the updated OS version number in System Preferences > General > About after restart.
