What is CVE-2026-90947?

A memory corruption vulnerability exists in GIMP's Lighting Effects filter, which fails to properly validate the number of light sources in specially crafted lighting preset files. This oversight can result in an out-of-bounds write, leading to memory corruption. An attacker could exploit this vulnerability by persuading a user to open a compromised preset file, which may result in application crashes or enable the execution of arbitrary code.
