Division by Zero in Linux Kernel Media Driver

Publication date: 2026-05-06

Last updated on: 2026-05-06

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.

Can you explain this vulnerability to me?

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.


How can this vulnerability impact me? :

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.
