Summary
In the Linux kernel, the following vulnerability has been resolved: media: nxp: imx8-isi: Fix potential out-of-bounds issues The maximum downscaling factor supported by ISI can be up to 16. Add minimum value constraint before applying the setting to hardware.
Otherwise, the process will not respond even when Ctrl+C is executed. A flaw was found in the NXP i.MX8 Image Sensor Interface (ISI) driver within the Linux kernel.
This out-of-bounds vulnerability arises from inadequate validation of the downscaling factor before it is applied to the hardware. A local attacker could exploit this to cause a denial of service, making the affected process unresponsive and unkillable.
Red Hat severity: Moderate — CVSS 4.7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-125.
Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Enterprise Linux for NVIDIA 26; Red Hat OpenShift Container Platform 4 as not affected.
