+CVE ID         : CVE-2023-0386 CVE-2023-31436 CVE-2023-32233
+
+Several vulnerabilities have been discovered in the Linux kernel that
+may lead to a privilege escalation, denial of service or information
+leaks.
+
+CVE-2023-0386
+
+    It was discovered that under certain conditions the overlayfs
+    filesystem implementation did not properly handle copy up
+    operations. A local user permitted to mount overlay mounts in user
+    namespaces can take advantage of this flaw for local privilege
+    escalation.
+
+CVE-2023-31436
+
+    Gwangun Jung reported a heap out-of-bounds read/write errors in the
+    traffic control subsystem for the Quick Fair Queueing scheduler
+    (QFQ) which may result in information leak, denial of service or
+    privilege escalation.
+
+CVE-2023-32233
+
+    Patryk Sondej and Piotr Krysiuk discovered a use-after-free flaw in
+    the Netfilter nf_tables implementation when processing batch
+    requests which may result in local privilege escalation for a user
+    with the CAP_NET_ADMIN capability in any user namespace.
