| Revision Date: | 2019-04-11 | Version: | 1 | | Title: | CVE-2019-3837 on Ubuntu 18.10 (cosmic) - medium. | | Description: | 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.
