What to do

Upgrade Linux kernel to 7.0.0-1010.10, 7.0.0-1009.9, 7.0.0-1008.8 or 7.0.0-27.27.

AI-suggested

An official patch is available and included in Linux kernel updates distributed by Ubuntu. Users should apply the update to versions 7.0.0-27.27 or later and reboot the system to complete remediation. Due to an ABI change in the kernel update, recompilation and reinstallation of all third-party kernel modules is required. Follow vendor guidance in Ubuntu Security Notice USN-8488-1 for detailed update instructions. No additional mitigation is required beyond applying the official fix.

Description

A use-after-free vulnerability (CVE-2026-46097) was identified and fixed in the Linux kernel's edt-ft5x06 input driver. The issue arose from a race condition during debugfs teardown where debugfs files remained accessible after a buffer was freed, potentially leading to memory corruption. The fix involves protecting the buffer freeing with a device mutex and nullifying the pointer to prevent unsafe access. This vulnerability affects multiple Linux kernel versions prior to 7.0.0-27.27 and related builds. A patch is available and included in standard Linux kernel updates distributed by Ubuntu. Users should update and reboot to apply the fix and recompile any third-party kernel modules due to ABI changes.
