CVE-2024-39475 Details
Description
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.
A vulnerability in the Linux kernel's Savage framebuffer driver can lead to a divide-by-zero error. This issue arises because the 'savagefb_probe' function does not properly handle error returns from 'savagefb_check_var', particularly when the 'pixclock' variable is zero. The vulnerability is present in the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The commit fixing this issue is available in the Linux kernel stable tree.
