AI-suggested
A patch is available and should be applied by upgrading to the fixed Linux kernel versions 5.15.0-1072.78~20.04.1 or later as listed in the established facts. Users of affected linux-azure kernel versions should update promptly to remediate this issue. No additional mitigation actions are indicated by the vendor advisory.
Description
CVE-2024-46732 is a medium severity vulnerability in the Linux kernel's AMD display driver subsystem where the linear_pitch_alignment value was not assigned in virtual machine (VM) environments. This omission could cause a divide-by-zero error leading to a denial of service (guest crash). The issue affects multiple specific linux-azure kernel versions prior to fixed releases. A patch is available and has been incorporated in updated kernel versions.
