What is CVE-2026-40916?

A vulnerability exists in GIMP's TIM image loader specifically within the 4BPP decoding path, allowing a local user to manipulate the application into a denial of service state. When opening a specially crafted TIM image file, the application crashes due to an unconditional overflow during the writing process to a variable-length array. This flaw highlights the importance of validating inputs and maintaining robust error-handling mechanisms to ensure software stability.
