Ubuntu Security Notice USN-8350-1
June 01, 2026

linux-nvidia-tegra vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-nvidia-tegra: Linux kernel for NVIDIA Tegra 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;
   - Packet sockets;
   - TLS protocol;
(CVE-2026-31419, CVE-2026-31504, CVE-2026-31533, CVE-2026-43033,
CVE-2026-43077, CVE-2026-43078, CVE-2026-46028)

Update instructions:

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

Ubuntu 24.04 LTS
   linux-image-6.8.0-1025-nvidia-tegra  6.8.0-1025.25
   linux-image-6.8.0-1025-nvidia-tegra-rt  6.8.0-1025.25
   linux-image-nvidia-tegra        6.8.0-1025.25
   linux-image-nvidia-tegra-6.8    6.8.0-1025.25
   linux-image-nvidia-tegra-rt     6.8.0-1025.25
   linux-image-nvidia-tegra-rt-6.8  6.8.0-1025.25

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.
