+<p>Several vulnerabilities have been discovered in the Linux kernel that
+may lead to the execution of arbitrary code, privilege escalation,
+denial of service or information leaks.</p>
+
+<ul>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-12351">CVE-2020-12351</a>
+
+    <p>Andy Nguyen discovered a flaw in the Bluetooth implementation in the
+    way L2CAP packets with A2MP CID are handled. A remote attacker in
+    short distance knowing the victim's Bluetooth device address can
+    send a malicious l2cap packet and cause a denial of service or
+    possibly arbitrary code execution with kernel privileges.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-12352">CVE-2020-12352</a>
+
+    <p>Andy Nguyen discovered a flaw in the Bluetooth implementation. Stack
+    memory is not properly initialised when handling certain AMP
+    packets. A remote attacker in short distance knowing the victim's
+    Bluetooth device address address can retrieve kernel stack
+    information.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-25211">CVE-2020-25211</a>
+
+    <p>A flaw was discovered in netfilter subsystem. A local attacker
+    able to inject conntrack Netlink configuration can cause a denial
+    of service.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-25643">CVE-2020-25643</a>
+
+    <p>ChenNan Of Chaitin Security Research Lab discovered a flaw in the
+    hdlc_ppp module. Improper input validation in the ppp_cp_parse_cr()
+    function may lead to memory corruption and information disclosure.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-25645">CVE-2020-25645</a>
+
+    <p>A flaw was discovered in the interface driver for GENEVE
+    encapsulated traffic when combined with IPsec. If IPsec is
+    configured to encrypt traffic for the specific UDP port used by the
+    GENEVE tunnel, tunneled data isn't correctly routed over the
+    encrypted link and sent unencrypted instead.</p></li>
+
+</ul>
+
+<p>For the stable distribution (buster), these problems have been fixed in
+version 4.19.152-1. The vulnerabilities are fixed by rebasing to the new
+stable upstream version 4.19.152 which includes additional bugfixes.</p>
+
+<p>We recommend that you upgrade your linux packages.</p>
