Affected Products:
SUSE Linux Enterprise Module for Public Cloud 15-SP2

An update that solves 11 vulnerabilities and has 62 fixes
is now available.


The SUSE Linux Enterprise 15 SP2 Azure kernel was updated to receive
various security and bugfixes.

The following security bugs were fixed:

- CVE-2021-3347: A use-after-free was discovered in the PI futexes during
fault handling, allowing local users to execute code in the kernel
- CVE-2021-3348: Fixed a use-after-free in nbd_add_socket that could be
triggered by local attackers (with access to the nbd device) via an I/O
request at a certain point during device setup (bnc#1181504).
- CVE-2021-20177: Fixed a kernel panic related to iptables string matching
rules. A privileged user could insert a rule which could lead to denial
of service (bnc#1180765).
- CVE-2021-0342: In tun_get_user of tun.c, there is possible memory
corruption due to a use after free. This could lead to local escalation
of privilege with System execution privileges required. (bnc#1180812)
- CVE-2020-27835: A use-after-free in the infiniband hfi1 driver was
found, specifically in the way user calls Ioctl after open dev file and
fork. A local user could use this flaw to crash the system (bnc#1179878).

leaks related to the PV block backend, as used by Xen (bnc#1179509).

watch events (bnc#1179508).
- CVE-2020-25211: Fixed a flaw where a local attacker was able to inject
conntrack netlink configuration that could cause a denial of service or
trigger the use of incorrect protocol numbers in
ctnetlink_parse_tuple_filter (bnc#1176395).
- CVE-2020-36158: Fixed an issue wich might have allowed a remote
attackers to execute arbitrary code via a long SSID value in
mwifiex_cmd_802_11_ad_hoc_start() (bnc#1180559).
- CVE-2020-28374: Fixed a vulnerability caused by insufficient identifier
checking in the LIO SCSI target code. This could have been used by a
remote attackers to read or write files via directory traversal in an
XCOPY request (bnc#1178372).
