USN-9002-1: Linux kernel (NVIDIA Tegra) vulnerabilities

Publication date

6 November 2026

Overview

Several security issues were fixed in the Linux kernel.

Releases

24.04 LTS

Packages

linux-nvidia-tegra - Linux kernel for NVIDIA Tegra systems

Details

It was discovered that the io_uring subsystem in the Linux kernel did not
properly handle canceled task work when processing certain wait operations,
leading to the operation being performed in the wrong task context. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2026-81010)

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:

ARM32 architecture;
ARM64 architecture;
MIPS architecture;
OpenRISC architecture;
PowerPC architecture;
RISC-V architecture;
S390 architecture;
x86 architecture;
Intel NPU Driver;
ACPI drivers;
Serial ATA and Parallel ATA drivers;
Auxiliary display drivers;
Ublk userspace block...

Update instructions

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

Learn more about how to get the fixes.

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.

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