Apple RTKit kernel memory protection bypass

IdentifiersCVE-2024-23296CWE-787· Out-of-bounds Write

CVE-2024-23296 is an Apple vulnerability described by Apple as a memory corruption issue in RTKit, the real-time operating system used on multiple Apple platforms. Apple states the issue was addressed through improved validation. Successful exploitation may allow an attacker who already has arbitrary kernel read and write capability to bypass kernel memory protections. Apple also reported that the issue may have been exploited in the wild. Fixed releases include iOS 16.7.8 and iPadOS 16.7.8, iOS 17.4 and iPadOS 17.4, macOS Monterey 12.7.6, macOS Ventura 13.6.7, macOS Sonoma 14.4, tvOS 17.4, visionOS 1.1, and watchOS 10.4.

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.

If exploited, the flaw enables bypass of kernel memory protections on affected Apple devices. In practical terms, this can weaken or defeat kernel hardening relied on to contain post-exploitation activity, making subsequent kernel-level exploitation more reliable and enabling deeper compromise of the device. Because Apple indicated the issue may have been exploited in the wild, the vulnerability has demonstrated operational relevance.

Mitigation

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

Where immediate patching is not possible, reduce exposure by prioritizing updates on internet-facing and high-risk user devices, enabling automatic updates, and monitoring for signs of kernel-level compromise or exploit-chain activity. Because the issue requires arbitrary kernel read/write capability, mitigating earlier-stage exploit vectors and limiting delivery of untrusted content can reduce practical exploitability, but no complete vendor-provided workaround is available in the supplied content.

Remediation

Patch, then assume compromise.

Upgrade affected systems to Apple versions containing the fix: iOS/iPadOS 16.7.8 or later for supported legacy devices, iOS/iPadOS 17.4 or later, macOS Monterey 12.7.6 or later, macOS Ventura 13.6.7 or later, macOS Sonoma 14.4 or later, tvOS 17.4 or later, visionOS 1.1 or later, and watchOS 10.4 or later. In enterprise environments, use MDM or equivalent fleet management to verify installed OS versions and accelerate deployment of Apple security updates.
