Publication date 14 April 2014
Last updated 24 July 2024
Ubuntu priority
drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable buffers are disabled, does not properly validate packet lengths, which allows guest OS users to cause a denial of service (memory corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to the handle_rx and get_rx_bufs functions.
From the Ubuntu Security Team
A flaw was discovered in the handling of network packets when mergeable buffers are disabled for virtual machines in the Linux kernel. Guest OS users may exploit this flaw to cause a denial of service (host OS crash) or possibly gain privilege on the host OS.
