CVE-2011-1927
Last modified
CVE-2011-1927 is a vulnerability of currently unknown severity. The ip_expire function in net/ipv4/ip_fragment.c in the Linux kernel before 2.6.39 does not properly construct ICMP_TIME_EXCEEDED packets after a timeout, which allows remote attackers to cause a denial of service (invalid pointer dereference) via crafted fragmented packets.. EPSS estimates a 2.59% chance of exploitation in the next 30 days.
