Name of the Vulnerable Software and Affected Versions SoftEtherVPN versions 5.02.5184 through 5.02.5187

Description The issue is related to a NULL dereference in the DeleteIPv6DefaultRouterInRA function called by StorePacket. This occurs because DeleteIPv6DefaultRouterInRA does not account for ParsePacket returning NULL, resulting in the program crashing.

Recommendations For versions 5.02.5184 through 5.02.5187, as a temporary workaround, consider disabling the DeleteIPv6DefaultRouterInRA function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
