From f2019796562a154044728afe0c80a71713fd55ec Mon Sep 17 00:00:00 2001 From: Nikita Shubin Date: Wed, 10 Apr 2024 07:59:18 +0000 Subject: [PATCH] ARM: ep93xx: Add terminator to gpiod_lookup_table stable inclusion from stable-v5.10.211 commit 70d92abbe29692a3de8697ae082c60f2d21ab482 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2O0 CVE: CVE-2024-26751 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=70d92abbe29692a3de8697ae082c60f2d21ab482 -------------------------------- Without the terminator, if a con_id is passed to gpio_find() that does not exist in the lookup table the function will not stop looping correctly, and eventually cause an oops.
