[PATCH OLK-6.6] iio: adc: at91: call input_free_device() on allocated iio_dev
by Wupeng Ma 06 Feb '25

06 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.
