| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to an implicit overflow on
virtio max dma size in the Linux kernel. Specifically, there is an implicit conversion from size t to u32 in the code: (u32)max size = (size t)virtio max dma size(vdev);. This conversion may lead to an overflow when virtio max dma size has a larger size than U32 MAX, resulting in a value of 0. For example, a size of (size t)4G would be converted to (u32)0. To prevent this, the code should use U32 MAX instead when virtio max dma size exceeds U32 MAX.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
