CVE-2024-46709

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

Description The issue is related to the drm/vmwgfx component in the Linux kernel, where external buffers might not provide direct access to readable/writable pages. To resolve this, the mapping of external buffers should go through the dma buf interface instead of trying to access pages directly. This fix prevents crashes in IGT's kms prime with vgem. The issue is not typically triggered by regular desktop usage due to the fact that virtual machines usually do not have multiple GPUs, but it enables better test coverage in IGT.

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