===================================================================== Red Hat Security Advisory
Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2020:4287-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2020:4287 Issue date: 2020-10-20 CVE Names: CVE-2020-12351 CVE-2020-12352 CVE-2020-14385 CVE-2020-14386 =====================================================================
1. Summary:
An update for kernel is now available for Red Hat Enterprise Linux 8.1 Extended Update Support.
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 CodeReady Linux Builder EUS (v. 8.1) - aarch64, ppc64le, x86_64 Red Hat Enterprise Linux BaseOS EUS (v. 8.1) - aarch64, noarch, ppc64le, s390x, x86_64
3. Description:
The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
* kernel: net: bluetooth: type confusion while processing AMP packets (CVE-2020-12351)
* kernel: net: bluetooth: information leak when processing certain AMP packets (CVE-2020-12352)
* kernel: metadata validator in XFS may cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt (CVE-2020-14385)
* kernel: memory corruption in net/packet/af_packet.c leads to elevation of privilege (CVE-2020-14386)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* NFS client autodisconnect timer may fire immediately after TCP connection setup and may cause DoS type reconnect problem in complex network environments (BZ#1873571)
* hang on full fs from trace_cmd (BZ#1875789)
* Secure boot key is not loaded with kernel-4.18.0-232.el8.x86_64 / shim-x64-15-15 (BZ#1877527)
* [RHEL-8.3] Kdump failed to start when secure boot enabled: kexec_file_load failed: Required key not available (BZ#1877529)
* [RHEL-8.3] Kdump/kexec kernel panicked on EFI boot: general protection fault: 0000 [#1] SMP PTI (BZ#1879987)
* [conntrack] udp packet reverse NAT occasionally fail when race condition request combination with the DNAT load balancing rules (BZ#1882096)
* [Regression] RHEL8.3 Beta - Do not initiate shutdown for EPOW_SHUTDOWN_ON_UPS event (BZ#1882244)
