Name of the Vulnerable Software and Affected Versions Linux Kernel (affected versions not specified)
Description The issue is related to a flaw in the Linux Kernel, specifically with the tun/tap sockets having their socket UID hardcoded to 0 due to a type confusion in their initialization function. This could lead to tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing network filters. The flaw is also associated with the use of an inappropriate data structure description for reading data from memory in the tap open() function of the TAP virtual network adapter driver.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
