UnknownEPSS 3.87%

Last modified

CVE-2009-1298 is a vulnerability of currently unknown severity. The ip_frag_reasm function in net/ipv4/ip_fragment.c in the Linux kernel 2.6.32-rc8, and 2.6.29 and later versions before 2.6.32, calls IP_INC_STATS_BH with an incorrect argument, which allows remote attackers to cause a denial of service (NULL pointer dereference and hang) via long IP packets, possibly related to the ip_defrag function.. EPSS estimates a 3.87% chance of exploitation in the next 30 days.
