CVE-2026-64165

Description

A flaw was found in the Linux kernel, specifically within the ARM Integrator/CP architecture. During early system initialization, a memory allocation function is called before the memory management system is fully ready. This can lead to a kernel crash, resulting in a Denial of Service (DoS) for the affected system. In some cases, it may also prevent the system clock from being properly registered.

Understanding the Weakness (CWE)

Availability

Technical Impact: DoS: Crash, Exit, or Restart

NULL pointer dereferences usually result in the failure of the process unless exception handling (on some platforms) is available and implemented. Even when exception handling is being used, it can still be very difficult to return the software to a safe state of operation.

Integrity,Confidentiality

Technical Impact: Execute Unauthorized Code or Commands; Read Memory; Modify Memory

In rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it, then writing or reading memory is possible, which may lead to code execution.
