UnknownEPSS 1.27%

Last modified

CVE-2003-0653 is a vulnerability of currently unknown severity. The OSI networking kernel (sys/netiso) in NetBSD 1.6.1 and earlier does not use a BSD-required "PKTHDR" mbuf when sending certain error responses to the sender of an OSI packet, which allows remote attackers to cause a denial of service (kernel panic or crash) via certain OSI packets.. EPSS estimates a 1.27% chance of exploitation in the next 30 days.
