5.5

Medium

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 The issue is related to a potential NULL pointer dereference in the ice bridge setlink() function. This can occur if nlmsg find attr() returns NULL and br spec is subsequently dereferenced in nla for each nested(). To address this, a check is added to ensure br spec is not NULL before proceeding with the nested attribute iteration.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
