CVE-2026-53332

Description

A flaw was found in the Linux kernel's Qualcomm NGD (Next Generation Display) controller (qcom-ngd-ctrl) component. This vulnerability arises from a race condition where callbacks are registered before the NGD device is fully initialized. This can lead to the callbacks operating on uninitialized data, potentially causing system instability, boot issues, and a denial of service on affected boards.

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.
