SUSE CVE-2013-4127

Use-after-free vulnerability in the vhostnetsetbackend function in drivers/vhost/net.c in the Linux kernel through 3.10.3 allows local users to cause a denial of service OOPS and system crash via vectors involving powering on a virtual machine...

SUSE CVE-2014-0055

The getrxbufs function in drivers/vhost/net.c in the vhost-net subsystem in the Linux kernel package before 2.6.32-431.11.2 on Red Hat Enterprise Linux RHEL 6 does not properly handle vhostgetvqdesc errors, which allows guest OS users to cause a denial of service host OS crash via unspecified...

SUSE CVE-2014-0077

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,...

SUSE CVE-2018-1118

Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhostnewmsg function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-ne...

SUSE CVE-2018-16880

A flaw was found in the Linux kernel's handlerx function in the vhostnet driver. A malicious virtual guest, under specific conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the...

SUSE CVE-2019-3900

An infinite loop issue was found in the vhostnet kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handlerx. It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stal...

In the Linux kernel before 5.5.8 get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field which might allow attackers to trigger kernel stack corruption via crafted system calls.

...

A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest under specific conditions can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.
