Kernel memory corruption in Apple operating systems

IdentifiersCVE-2024-44245CWE-787· Out-of-bounds Write

CVE-2024-44245 is a memory-handling vulnerability in Apple software that can allow an app to trigger unexpected system termination or corrupt kernel memory. Apple states the issue was addressed with improved memory handling and fixed in iPadOS 17.7.3, visionOS 2.2, macOS Sequoia 15.2, iOS 18.2 and iPadOS 18.2, and macOS Sonoma 14.7.2. The available advisory text does not identify the specific vulnerable component or function, but the impact description places the flaw in a kernel-relevant code path where malformed or attacker-controlled operations from an app can destabilize the system or damage kernel memory.

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 may cause a kernel panic or other unexpected system termination, resulting in denial of service. Because the flaw can corrupt kernel memory, it may also create conditions for more serious compromise, including potential escalation of impact beyond a simple crash, although the provided Apple text does not explicitly confirm code execution or privilege escalation for this CVE.

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 applications, enforcing application allowlisting where feasible, and restricting local user access on affected devices. Because the described attack path is app-driven, MDM controls, least-privilege local access, and rapid update deployment are the most relevant interim mitigations. No vendor-specific workaround beyond updating is provided in the supplied content.

Remediation

Patch, then assume compromise.

Apply the vendor fixes provided by Apple. Apple states the issue is fixed in iPadOS 17.7.3, visionOS 2.2, macOS Sequoia 15.2, iOS 18.2 and iPadOS 18.2, and macOS Sonoma 14.7.2. Systems running affected earlier versions should be upgraded to the corresponding patched release.
