- CWE-787
Description
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.
Affected configurations
• linux linux kernel (>= 4.16 < 4.19.20)
• linux linux kernel (>= 4.20 < 4.20.7)
• canonical ubuntu linux 18.04
• canonical ubuntu linux 18.10
