Linux Kernel (NVIDIA Tegra) Vulnerabilities — Ubuntu Security Update (USN-9002-1)

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.
