CVE-2026-64049

Description

A flaw was found in the Linux kernel's Adreno Graphics Processing Unit (GPU) driver. This vulnerability allows a local user to trigger a system crash by querying unsupported Universal Bandwidth Compression (UBWC) parameters from userspace. This can lead to a Denial of Service (DoS), making the system unavailable.

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.
