Multiple security fixes for Linux kernel in Ubuntu improve system protection. Update promptly to safeguard against attacks.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-nvidia-tegra-igx: Linux kernel for NVIDIA Tegra IGX systems

Details:

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)

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;

- 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)

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS
   linux-image-5.15.0-1049-nvidia-tegra-igx  5.15.0-1049.49
   linux-image-5.15.0-1049-nvidia-tegra-igx-rt  5.15.0-1049.49
   linux-image-nvidia-tegra-igx    5.15.0.1049.51
   linux-image-nvidia-tegra-igx-5.15  5.15.0.1049.51
   linux-image-nvidia-tegra-igx-rt  5.15.0.1049.51
   linux-image-nvidia-tegra-igx-rt-5.15  5.15.0.1049.51

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
