CWE Code: 119
Vulnerability Type: privilege_escalation
CVSS Score: 4.9
CWE Name:  Improper Restriction of Operations within the Bounds of a Memory Buffer
Summary: it was found that the net_dma code in tcp_recvmsg() in the 2.6.32 kernel as shipped in rhel6 is thread-unsafe. so an unprivileged multi-threaded userspace application calling recvmsg() for the same network socket in parallel executed on ioatdma-enabled hardware with net_dma enabled can leak the memory, crash the host leading to a denial-of-service or cause a random memory corruption.
Access Authentication: NONE
Access Complexity: LOW
Access Vector: LOCAL
Impact (C/I/A): NONE/NONE/COMPLETE
