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

Ubuntu • November 6, 2026

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...

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.

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

Reduce your security exposure

Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
