Official description

In the Linux kernel, the following vulnerability has been resolved: Input: edt-ft5x06 - fix use-after-free in debugfs teardown The commit 68743c500c6e ("Input: edt-ft5x06 - use per-client debugfs directory") removed the manual debugfs teardown, relying on the I2C core to handle it. However, this creates a window where debugfs files are still accessible after edt_ft5x06_ts_teardown_debugfs() frees tsdata->raw_buffer. To prevent a use-after-free, protect the freeing of raw_buffer with the device mutex and set raw_buffer to NULL. The debugfs read function already checks if raw_buffer is NULL under the same mutex, so this safely avoids the use-after-free.
