It was discovered that the Linux kernel algif_aead module did not properly
handle in-place cryptographic operations. This flaw is known as Copy Fail.
A local attacker could use this to escalate privileges, or possibly escape
a container. (CVE-2026-31431)
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)
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)
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)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- Cryptographic API;
- Ethernet bonding driver;
- SMB network file system;
- Netfilter;
- io_uring subsystem;
- Packet sockets;
- RDS protocol;
- TLS protocol;
(CVE-2024-35862, CVE-2024-50060, CVE-2026-23274, CVE-2026-23351,
CVE-2026-31419, CVE-2026-31504, CVE-2026-31533, CVE-2026-43033,
CVE-2026-43077, CVE-2026-43078, CVE-2026-43494, CVE-2026-46028)

It was discovered that lwIP contained a buffer overflow in the EAP
authentication handling code. An attacker could possibly use this issue
to trigger a buffer overflow, resulting in arbitrary code execution or a
denial of service. This issue only affected Ubuntu 20.04 LTS.
(CVE-2020-8597)
It was discovered that lwIP incorrectly handled certain ICMPv6 or
6LoWPAN packets. An attacker could possibly use this issue to trigger a
buffer overflow, resulting in information disclosure. This issue only
affected Ubuntu 20.04 LTS. (CVE-2020-22283, CVE-2020-22284)
It was discovered that lwIP did not properly validate certain SNMPv3
authentication parameters. An attacker could possibly use this issue to
trigger a stack-based buffer overflow, resulting in arbitrary code
execution or a denial of service. (CVE-2026-8836)
