AI-suggested

A patch is available and should be applied immediately. Update the system to linux-nvidia-tegra-5.15 version 5.15.0-1068.70~20.04.1 or later. After updating, a system reboot is required to apply all changes. Due to an ABI change, third-party kernel modules must be recompiled and reinstalled. Follow the vendor's update instructions as detailed in the Ubuntu security notice USN-8849-1. No other mitigation is indicated or required.

Description

A vulnerability in the Linux kernel for NVIDIA Tegra systems (CVE-2025-10263) affects certain ARM processors where a broadcast translation lookaside buffer (TLB) invalidation can complete before memory writes through the invalidated translation are globally observed. This flaw allows a local attacker to write to memory after permission has been revoked, potentially bypassing memory protections or escalating privileges. Multiple other security issues in various Linux kernel subsystems were also addressed in the same update.
