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.
Affected configurations
• linux linux kernel (>= 6.17 < 6.18.27)
• linux linux kernel (>= 6.19 < 7.0.4)
