Linux Kernel Refcount Leak Vulnerability in Display Timing Handling

CVE-2026-43264

What is CVE-2026-43264?

A refcount leak vulnerability exists in the Linux kernel's handling of display timings. The issue arises in the code responsible for managing the reference count of device nodes. When an error occurs, the reference count for a device node is not decremented properly, leading to a potential resource leak. The vulnerability is mitigated by adjusting the error handling logic to ensure that the reference count is correctly managed, preventing unnecessary memory consumption and ensuring overall system stability.
