CVE-2010-4526: Linux Kernel

High severity, CVSS 7.1. EPSS: 2.5% chance of exploitation in the next 30 days.

Race condition in the sctp_icmp_proto_unreachable function in net/sctp/input.c in Linux kernel 2.6.11-rc2 through 2.6.33 allows remote attackers to cause a denial of service (panic) via an ICMP unreachable message to a socket that is already locked by a user, which causes the socket to be freed and triggers list corruption, related to the sctp_wait_for_connect function.

Affected products

  • Linux Linux Kernel: from 2.6.11.1, up to and including 2.6.33; version 2.6.11 only
  • Red Hat Enterprise Mrg: version 1.0 only
  • VMware Esx: version 4.0 only; version 4.1 only
