CVE-2026-43182

Medium

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.
