CVE-2026-72267

Local service degradation via framebuffer modelist leak

Published Aug 15, 2026 · Updated Aug 15, 2026

A memory leak in Linux kernel carminefb allows local users to reduce available kernel memory through a framebuffer setup error. The driver allocates a modelist in fb_videomode_to_modelist(), then leaves a later failure branch without calling fb_destroy_modelist(). Exploitation requires local low-privilege access and the affected carminefb initialization path; impact is limited to kernel-memory consumption.
