SUSE Linux Enterprise Module for Realtime 15-SP2
______________________________________________________________________________
An update that solves 10 vulnerabilities and has 61 fixes is now available.
Description:
The SUSE Linux Enterprise 15 SP2 realtime kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:

fault handling, allowing local users to execute code in the kernel (bnc#
1181349).
o 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).

rules. A privileged user could insert a rule which could lead to denial of
service (bnc#1180765).

watch events (bnc#1179508).
o 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).
