CVE-2024-46712

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue concerns the use of coherent dumb buffers in configurations without 3D enabled. Coherent surfaces are only useful when the host renders to them using accelerated APIs. Without 3D, the content of dumb buffers stays in the guest, making synchronization efforts between the guest and host unnecessary. Configurations without 3D tend to have low graphics memory limits, leading to issues with console feedback, mouse cursors, and graphical login managers running out of the 16MB graphics memory. The fix involves ensuring coherent dumb buffers are only used on configurations with 3D enabled.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
