Description Agostino Sarubbo gentoo-dev 2014-04-01 10:42:03 UTC 
CVE-2014-2673 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-2673):

The arch_dup_task_struct function in the Transactional Memory (TM) implementation in 
arch/powerpc/kernel/process.c in the Linux kernel before 3.13.7 on the powerpc platform does not properly 
interact with the clone and fork system calls, which allows local users to cause a denial of service 
(Program Check and system crash) via certain instructions that are executed with the processor in the 
Transactional state.
