VectorAV: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 A flaw exists in the Linux kernel's ksmd and smbd components related to the dma unmap sg() function. The issue arises because dma unmap sg() is called with an incorrect number of segments, specifically using the return value of the dma map sg() function instead of the original input. This can lead to memory management problems.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
