CVE-2026-43146
Description
A flaw was found in the Linux kernel's iris media driver. When creating internal buffers, a buffer was added to a list before its Direct Memory Access (DMA) allocation was successfully completed. If the DMA allocation failed, a partially initialized buffer remained in the list. This could lead to an inconsistent system state and potential memory leaks.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory; Read Application Data
When reusing a resource such as memory or a program variable, the original contents of that resource may not be cleared before it is sent to an untrusted party.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
The uninitialized resource may contain values that cause program flow to change in ways that the programmer did not intend.
