Synopsis: Important: kernel security, bug fix, and enhancement update Advisory ID: RHSA-2021:1272-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:1272 Issue date: 2021-04-20 CVE Names: CVE-2021-3347 CVE-2021-27363 CVE-2021-27364 CVE-2021-27365 =====================================================================
1. Summary:
An update for kernel is now available for Red Hat Enterprise Linux 8.2 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. 8.2) - aarch64, ppc64le, x86_64 Red Hat Enterprise Linux BaseOS EUS (v. 8.2) - 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: Use after free via PI futex state (CVE-2021-3347)
* kernel: out-of-bounds read in libiscsi module (CVE-2021-27364)
* kernel: heap buffer overflow in the iSCSI subsystem (CVE-2021-27365)
* kernel: iscsi: unrestricted access to sessions and handles (CVE-2021-27363)
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.
