NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-firmware package and not the kernel-uek-firmware package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

fbdev: savage: Handle err return when savagefb_check_var failed

The commit 04e5eac8f3ab("fbdev: savage: Error out if pixclock equals zero") checks the value of pixclock to avoid divide-by-zero error. However the function savagefb_probe doesn't handle the error return of savagefb_check_var. When pixclock is 0, it will cause divide-by-zero error.
