Doc Text:
A flaw was found in the Linux kernel's media: ccs component. This vulnerability, a division-by-zero error, occurs when calculating the maximum M for scaler configuration. A missing check for a non-zero value in the MIN_X_OUTPUT_SIZE limit register could allow a local attacker to trigger a system crash. This could lead to a denial of service (DoS).

Description OSIDB Bzimport 2026-05-06 13:04:46 UTC
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.
