Description

A flaw was found in the Linux kernel, specifically within the `auxdisplay` and `line-display` modules. This vulnerability occurs when the `linedisp_release()` function attempts to free display resources. If the associated attachment list has already been removed, the function dereferences a null pointer, which can lead to a system crash. This issue results in a Denial of Service (DoS), making the system unavailable.
