[PATCH openEuler-1.0-LTS] HID: multitouch: Correct devm device reference for hidinput input_dev name
by Lin Ruifeng 27 Oct '25

From: Rahul Rameshbabu <sergeantsagara(a)protonmail.com> stable inclusion from stable-v4.19.295 commit 39c70c19456e50dcb3abfe53539220dff0490f1d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID0REB CVE:CVE-2023-53454 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4794394635293a3e74591351fff469cea7ad15a2 ] Reference the HID device rather than the input device for the devm allocation of the input_dev name. Referencing the input_dev would lead to a use-after-free when the input_dev was unregistered and subsequently fires a uevent that depends on the name. At the point of firing the uevent, the name would be freed by devres management. Use devm_kasprintf to simplify the logic for allocating memory and formatting the input_dev name string.

However, the data left for the last pos may be < sizeof(struct sctp_ifwdtsn_skip), and dereference it as struct sctp_ifwdtsn_skip may cause coverflow.

[PATCH OLK-6.6] regulator: core: fix NULL dereference on unbind due to stale coupling data

This can happen during runtime PM or other regulator operations that rely on coupling metadata. For example, on ridesx4, unbinding the 'reg-dummy' platform device triggers a panic in regulator_lock_recursive() due to stale coupling state.
