Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the debugfs teardown process of the edt-ft5x06 driver. The removal of manual debugfs teardown created a window where debugfs files remain accessible after the edt ft5x06 ts teardown debugfs() function frees the raw buffer variable within tsdata. This occurs because the I2C core handles the teardown, but the buffer is released prematurely.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
