This mitigation requires updated CPU microcode provided in the intel-microcode package. For details please refer to and . CVE-2023-20569 Daniel Trujillo, Johannes Wikner and Kaveh Razavi discovered INCEPTION, also known as Speculative Return Stack Overflow (SRSO), a transient execution attack that leaks arbitrary data on all AMD Zen CPUs. An attacker can mis-train the CPU BTB to predict non- architectural CALL instructions in kernel space and use this to control the speculative target of a subsequent kernel RET, potentially leading to information disclosure via a speculative side-channel. For details please refer to and . For the oldstable distribution (bullseye), these problems have been fixed in version 5.10.179-5. For the stable distribution (bookworm), these problems have been fixed in version 6.1.38-4. We recommend that you upgrade your linux packages.

Red Hat OpenStack 10.0 RHSA-2018:1644-01 Important Qemu-KVM-RHEV Update

An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform 10.0 (Newton). Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score,. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: qemu-kvm-rhev security update Advisory ID: RHSA-2018:1644-01 Product: Red Hat Enterprise Linux OpenStack Platform Advisory URL: https://access.redhat.com/errata/RHSA-2018:1644 Issue date: 2018-05-21 CVE Names: CVE-2018-3639 ==================================================================== 1. Summary: An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform 10.0 (Newton). Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat OpenStack Platform 10.0 - x86_64 3. Description: KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products. Security Fix(es): * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that neveractually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639) Note: This is the qemu-kvm-rhev side of the CVE-2018-3639 mitigation. Red Hat would like to thank Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project Zero) for reporting this issue. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect. 5. Bugs fixed (https://bugzilla.redhat.com/): 1566890 - CVE-2018-3639 hw: cpu: speculative store bypass 6.
