Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a divide-by-zero error in the
savagefb check var() function. A userspace program can pass any values to the driver through the ioctl() interface, potentially causing a divide-by-zero error if the pixclock value is not properly checked. The error occurs because pixclock is not checked properly in savagefb probe(), although it is checked in savagefb decode var(). The fix involves checking whether pixclock is zero in the savagefb check var() function before using info->var.pixclock as the divisor.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
