Kernel: vhost_net: infinite loop while receiving packets leads to DoS

An infinite loop issue was found in the vhostnet kernel module while handling incoming packets in handlerx. The infinite loop could occur if one end sends packets faster than the other end can process them. A guest user, maybe a remote one, could use this flaw to stall the vhostnet kernel thread,...

Information Disclosure

Linux kernel is vulnerable to information disclosure vulnerability. This is because Linux kernel does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhostnewmsg function. A privileged user could read some memory contents...

DEBIAN-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...

Name of the Vulnerable Software and Affected Versions Linux Kernel versions up to and including v5.1-rc6 Description The issue is related to an infinite loop in the vhost net kernel module when handling incoming packets in the handle rx function. This can happen if one end sends packets faster th...

Linux kernel Handle Rx Memory Corruption

The vulnerability of the handlerx function in the vhostnet driver of the Linux operating system is related to writing data beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause damage to the kernel’s memory...

USN-3903-2 linux-hwe, linux-azure vulnerabilities

USN-3903-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.10. This update provides the corresponding updates for the Linux Hardware Enablement HWE kernel from Ubuntu 18.10 for Ubuntu 18.04 LTS. Jason Wang discovered that the vhost net driver in the Linux kernel contained an out of bounds...

USN-3903-1: Linux kernel vulnerabilities

Jason Wang discovered that the vhost net driver in the Linux kernel contained an out of bounds write vulnerability. An attacker in a guest virtual machine could use this to cause a denial of service host system crash or possibly execute arbitrary code in the host kernel. CVE-2018-16880 Jann Horn...

DEBIAN-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...
