Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a DMA mappings leak in the Linux kernel's ice component. This leak occurs when a user changes ring parameters, and new DMA mappings are created for RX buffers without properly substituting older ones. The
ice vsi cfg rxq function frees these buffers, and they are reallocated again with ice alloc rx buf, causing a leak of already mapped DMA. This can be exploited to cause a denial of service. The vulnerability can be reproduced by running a script that changes the RX and TX ring parameters using the ethtool command.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
