Linux Kernel Sitronix ST7701 Panel Driver Memory Leak Vulnerability

A vulnerability exists in the Linux kernel's handling of the Sitronix ST7701 panel driver. When the MIPI DSI attachment process fails, the driver does not properly remove the panel, leading to a memory leak. This issue is present in the Linux kernel stable tree.

Impact

The vulnerability can cause a memory leak, which may lead to increased memory usage and potential exhaustion of system resources.

Reproduction

The vulnerability can be reproduced by attempting to attach a Sitronix ST7701 panel via the MIPI DSI interface. If the attachment fails, the driver will not remove the panel properly, causing a memory leak.

Remediation

The vulnerability has been addressed in a patch that removes the panel during a DSI attachment failure. This patch is available in the Linux kernel stable tree.
