CVE-2026-68225

Host crash via unchecked control pointer

Published Aug 10, 2026 · Updated Aug 10, 2026

A NULL-pointer write in the Linux kernel's Alvium CSI-2 camera driver allows local users to crash the host during control initialization. In drivers/media/i2c/alvium-csi2.c, alvium_ctrl_init() sets flags through control pointers without checking whether control creation returned NULL. Reaching the faulty initialization path requires compatible Alvium camera hardware; the resulting invalid kernel write interrupts service by crashing the host.
