kernel: memory leak in tcp_recvmsg() with NET_DMA

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.

Dell/Alienware Digital Delivery versions prior to 4.0.41 contain a privilege escalation vulnerability. A local non-privileged malicious user could exploit a Universal Windows Platform application by manipulating the install software package feature with a race condition and a path traversal exploit in order to run a malicious executable with elevated privileges.

Debian tmpreaper version 1.6.13+nmu1 has a race condition when doing a (bind) mount via rename() which could result in local privilege escalation. Mounting via rename() could potentially lead to a file being placed elsewhereon the filesystem hierarchy (e.g. /etc/cron.d/) if the directory being cleaned up was on the same physical filesystem. Fixed versions include 1.6.13+nmu1+deb9u1 and 1.6.14.

kernel: kvm: Information leak within a KVM guest

In a Linux KVM guest that has PV TLB enabled, a process in the guest kernel may be able to read memory locations from another process in the same guest. This problem is limit to the host running linux kernel 4.10 with a guest running linux kernel 4.16 or later. The problem mainly affects AMD processors but Intel CPUs cannot be ruled out.
