Name of the Vulnerable Software and Affected Versions
Linux kernel versions from v4.16 and newer
Description
A flaw in the Linux kernel's handle rx() function in the vhost net driver can be exploited by a malicious virtual guest to trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host. This may lead to kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.
Recommendations
For Linux kernel versions from v4.16 and newer, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
