CVE-2026-64358

Description

A flaw was found in the Linux kernel's media component, specifically within the mtk-jpeg driver. An internal function attempts to cancel a background task even when that task is not active on certain system configurations. This can lead to the system logging warning messages, potentially causing minor system instability or unexpected behavior. This issue does not result in critical security impacts such as data compromise or unauthorized code execution.

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.
