CVE-2023-53700

Local service interruption via leaked V4L2 controls

Published Oct 22, 2025 · Updated Oct 22, 2025

Memory leakage in affected Linux kernels allows local users to interrupt service by repeatedly triggering MAX9286 probe failures. In drivers/media/i2c/max9286.c, max9286_v4l2_register() allocates a V4L2 control through v4l2_ctrl_new_std() but does not free it when endpoint lookup fails. The path requires local access to a MAX9286 device or equivalent mock setup; repeated failed probes consume kernel memory and can hang or crash the system.
