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
