Sensitive kernel state leak in Apple Kernel logging

IdentifiersCVE-2026-28987CWE-532· Insertion of Sensitive Information…

CVE-2026-28987 is an Apple Kernel information disclosure vulnerability caused by a logging issue. Apple states that insufficient redaction in kernel-related logging could allow an app to leak sensitive kernel state. The issue was addressed by improved data redaction. Affected platforms called out in the provided content include iOS 18.7.9 and iPadOS 18.7.9, iOS 26.5 and iPadOS 26.5, macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5, tvOS 26.5, and watchOS 26.5.

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 allows a local app to obtain sensitive kernel state information. While the provided content does not describe direct code execution or privilege escalation from this CVE alone, disclosure of kernel state can weaken kernel exploit mitigations, aid vulnerability research, improve exploit reliability, and support chaining with other kernel memory corruption or privilege-escalation flaws.

Mitigation

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

If immediate patching is not possible, reduce exposure by limiting installation and execution of untrusted or unnecessary apps, enforcing application control/MDM policies on managed devices, and restricting local code execution where feasible. No vendor-provided workaround beyond updating is present in the supplied content.

Remediation

Patch, then assume compromise.

Apply the vendor fixes released by Apple. The issue is fixed in iOS 18.7.9 and iPadOS 18.7.9, iOS 26.5 and iPadOS 26.5, macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5, tvOS 26.5, and watchOS 26.5.
