CVE-2015-8615 (GCVE-0-2015-8615)

Vulnerability from cvelistv5 – Published: 2016-01-08 19:00 – Updated: 2024-08-06 08:20

Summary

The hvm_set_callback_via function in arch/x86/hvm/irq.c in Xen 4.6 does not limit the number of printk console messages when logging the new callback method, which allows local HVM guest OS users to cause a denial of service via a large number of changes to the callback method (HVM_PARAM_CALLBACK_IRQ).

Severity

No CVSS data available.
