Linux Kernel Out-of-Bounds Access Vulnerability in IMX JPEG Media Component

A vulnerability in the Linux kernel's IMX JPEG media component allows for out-of-bounds array access. This issue arises when an error occurs while parsing JPEG files, leading to the use of an incorrect slot number. As a result, the driver modifies the 'num_domains' parameter, which is linked to 'slot_data' in the 'mxc_jpeg_dev' structure. This improper handling prevents the driver from detaching the power management domain during module removal, causing a kernel panic when attempting to reload the module.

Impact

Exploitation of this vulnerability leads to a kernel panic, causing system instability and disruption of services.
