29 Apr. 2013
Summary
Xen drivers/xen/pciback/conf_space_capability_msi.c pciback_enable_msi() function kernel log message saturation local suffers from denial of servic vulnerability
Xen contains a flaw in the pciback_enable_msi() function of drivers/xen/pciback/conf_space_capability_msi.c that may allow a local denial of service. The issue is due to the program failing to restrict kernel log messages. With a saturation of Kernel Log messages, a local attacker can cause the exhaustion of system resources.
