CVE-2009-4272 (GCVE-0-2009-4272)

Vulnerability from cvelistv5 – Published: 2010-01-27 17:00 – Updated: 2024-08-07 06:54
VLAI
Summary
A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (deadlock) via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chain is too long. NOTE: this is related to an issue in the Linux kernel before 2.6.31, when the kernel routing cache is disabled, involving an uninitialized pointer and a panic.
