Division by Zero in Linux Kernel Media Driver

Publication date: 2026-05-06

Last updated on: 2026-05-11

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: media: ccs: Avoid possible division by zero Calculating maximum M for scaler configuration involves dividing by MIN_X_OUTPUT_SIZE limit register's value. Albeit the value is presumably non-zero, the driver was missing the check it in fact was. Fix this.

Executive Summary

This vulnerability exists in the Linux kernel's media subsystem, specifically in the ccs driver. It involves a missing check for a division by zero condition when calculating the maximum M value for scaler configuration. The calculation divides by the value of the MIN_X_OUTPUT_SIZE limit register, which was assumed to be non-zero, but the driver did not verify this assumption, potentially leading to a division by zero error.

Impact Analysis

If exploited, this vulnerability could cause a division by zero error in the Linux kernel's media driver, which may lead to system instability or crashes. This could affect the reliability of media processing on affected systems.
