Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions: NetBSD versions 1.6.1 and earlier

Description: The issue concerns the OSI networking kernel in NetBSD, which fails to use a required PKTHDR mbuf when sending certain error responses. This allows remote attackers to cause a denial of service, potentially leading to a kernel panic or crash, by sending specific OSI packets.

Recommendations: For NetBSD versions 1.6.1 and earlier, consider upgrading to a version that includes the necessary fix to prevent the denial of service. As a temporary workaround, restrict access to the OSI networking kernel to minimize the risk of exploitation.
