  script_tag(name:"insight", value:"This kernel-linus update is based on upstream 5.15.120 and fixes at least
the following security issues:

A flaw null pointer dereference in the Linux kernel DECnet networking
protocol was found. A remote user could use this flaw to crash the
system. This is fixed by removing DECnet support (CVE-2023-3338).

A use-after-free vulnerability was found in the Linux kernel's netfilter
subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with
NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same
transaction causing a use-after-free vulnerability. This flaw allows a
local attacker with user access to cause a privilege escalation issue
(CVE-2023-3390).

NOTE!!
This kernel also contains a fix for dkms builds hanging / stalling during
upgrade to Mageia 9 (mga#31982) due to the new make 4.4 series utility
ending up in a loop processing Makefile in kernel-devel packages.
So if you use dkms packaged drivers and kernel-linus, you need to be
running this kernel (or any later released ones) before you do an online
upgrade to avoid the upgrade stalling / hanging.

For other upstream fixes in this update, see the referenced changelogs.");
