[PATCH OLK-6.6] iio: adc: at91: call input_free_device() on allocated iio_dev
by Wupeng Ma 17 Feb '25
by Wupeng Ma 17 Feb '25
17 Feb '25
From: Joe Hattori <joe(a)pf.is.s.u-tokyo.ac.jp>
stable inclusion
from stable-v6.6.72
commit 09e067e3c83e0695d338e8a26916e3c2bc44be02
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIQWA
CVE: CVE-2024-57904
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit de6a73bad1743e9e81ea5a24c178c67429ff510b upstream.
Current implementation of at91_ts_register() calls input_free_deivce()
on st->ts_input, however, the err label can be reached before the
allocated iio_dev is stored to st->ts_input. Thus call
input_free_device() on input instead of st->ts_input.
Fixes: 84882b060301 ("iio: adc: at91_adc: Add support for touchscreens without TSMR")
