CVE-2018-16880 (GCVE-0-2018-16880)

Vulnerability from cvelistv5 – Published: 2019-01-29 16:00 – Updated: 2024-08-05 10:32

Summary

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.

Severity

5.9 (Medium)
