  script_tag(name:"insight", value:"This kernel-linus update is based on upstream 5.10.11 and fixes at least the
following security issue:

SCSI 'EXTENDED COPY' (XCOPY) requests sent to a Linux SCSI target (LIO)
allow an attacker to read or write anywhere on any LIO backstore configured
on the host, provided the attacker has access to one LUN and knowledge of
the victim backstore's vpd_unit_serial (AKA 'wwn'). This is possible
regardless of the transport/HBA settings for the victim backstore
(CVE-2020-28374).

fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8, when there is an NFS
export of a subdirectory of a filesystem, allows remote attackers to
traverse to other parts of the filesystem via READDIRPLUS (CVE-2021-3178).

It also adds the following fix:
- fix up kernel-devel packages to not cause errors during dkms installs
 (mga#27080)");
