      <title>CVE-2023-3090 — Out-of-bounds write in Linux kernel's ipvlan network driver</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2023-3090</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux Kernel&lt;/p&gt;
&lt;p&gt;A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation.&lt;/p&gt;
&lt;p&gt;The out-of-bounds write is caused by missing skb-&amp;gt;cb  initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled.&lt;/p&gt;
&lt;p&gt;We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e.&lt;/p&gt;</description>
