CVE-2015-6654 (GCVE-0-2015-6654)

Vulnerability from cvelistv5 – Published: 2015-09-03 14:00 – Updated: 2024-08-06 07:29

Summary

The xenmem_add_to_physmap_one function in arch/arm/mm.c in Xen 4.5.x, 4.4.x, and earlier does not limit the number of printk console messages when reporting a failure to retrieve a reference on a foreign page, which allows remote domains to cause a denial of service by leveraging permissions to map the memory of a foreign guest.

Severity

No CVSS data available.
