| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol. This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the system. The vulnerability is related to the incorrect calculation of the packet header size in the
ipv6 rpl segdata pos() function in the net/ipv6/rpl.c module. The issue can be exploited by sending specially crafted IPv6 packets, potentially leading to a system crash.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
