CVE-2018-5332

Status Candidate

Overview

In the Linux kernel through 4.14.13, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c).

Ubuntu Security Notice USN-3632-1
Posted Apr 24, 2018
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3632-1 - It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM subsystem of the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the KVM implementation in the Linux kernel allowed passthrough of the diagnostic I/O port 0x80. An attacker in a guest VM could use this to cause a denial of service in the host OS. Various other issues were also addressed.

Ubuntu Security Notice 3620-2 - USN-3620-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 ESM. Jann Horn discovered that microprocessors utilizing speculative execution and branch prediction may allow unauthorized memory reads via sidechannel attacks. This flaw is known as Spectre. A local attacker could use this to expose sensitive information, including kernel memory. Various other issues were also addressed.

Red Hat Security Advisory 2018-0470-01 - Red Hat Enterprise MRG is a next-generation IT infrastructure for enterprise computing. MRG offers increased performance, reliability, interoperability, and faster computing for enterprise customers. Security Fix: kernel: rds_message_alloc_sgs() function doesn't validate value used during DMA page allocation causes heap out-of-bounds write kernel: Null pointer dereference in rds_atomic_free_op() allows denial-of-service.
