      <title>CVE-2026-47337 — NULL pointer dereference in Ubuntu Linux AppArmor IPv4/IPv6 socket mediation</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-47337</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Canonical Ubuntu Linux&lt;/p&gt;
&lt;p&gt;Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches with a possible NULL pointer dereference in the handling of AF_INET/AF_INET6 socket mediation. The bug can be triggered by an unprivileged local user. This can lead to a kernel oops.&lt;/p&gt;</description>

      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Ubuntu:26.04:LTS: linux, Ubuntu:26.04:LTS: linux-aws, Ubuntu:26.04:LTS: linux-gcp, Ubuntu:26.04:LTS: linux-ibm, Ubuntu:26.04:LTS: linux-nvidia, Ubuntu:26.04:LTS: linux-oracle, Ubuntu:26.04:LTS: linux-raspi, Ubuntu:26.04:LTS: linux-realtime&lt;/p&gt;
&lt;p&gt;It was discovered that the Linux kernel did not properly handle shared page
fragments during socket buffer operations, collectively known as Dirty
Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the
RxRPC networking subsystem when processing paged fragments. A local
attacker could use this to escalate privileges, or possibly escape a
container. (CVE-2026-43284, CVE-2026-43500, CVE-2026-45998, CVE-2026-46000)&lt;/p&gt;
&lt;p&gt;It was discovered that a logic flaw existed in the XFRM ESP-in-TCP
subsystem in the Linux kernel when handling socket buffer fragments. This
flaw is known as Fragnesia. A local attacker could use this to escalate
privileges, or possibly escape a container. (CVE-2026-43503,
CVE-2026-46300)&lt;/p&gt;
&lt;p&gt;Qualys discovered that a race condition existed in the ptrace subsystem of
the Linux kernel when privileged processes are exiting. An unprivileged
local attacker could use this issue to expose sensitive information.
(CVE-2026-46333)&lt;/p&gt;
&lt;p&gt;Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0
contain a memory leak when handling AppArmor notifications. A local
attacker could use this to cause resource exhaustion. (CVE-2026-47326)&lt;/p&gt;
