[PATCH OLK-6.6] hwmon: (hp-wmi-sensors) Check if WMI event data exists

From: Armin Wolf <W_Armin(a)gmx.de> stable inclusion from stable-v6.6.51 commit 217539e994e53206bbf3fb330261cc78c480d311 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IARWCY CVE: CVE-2024-46768 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit a54da9df75cd1b4b5028f6c60f9a211532680585 ] The BIOS can choose to return no event data in response to a WMI event, so the ACPI object passed to the WMI notify handler can be NULL.

[PATCH OLK-6.6] nilfs2: protect references to superblock parameters exposed in sysfs
by Zhao Wenhui 27 Sep '24

27 Sep '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v6.6.51 commit 8c6e43b3d5f109cf9c61bc188fcc8175404e924f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IARYCR CVE: CVE-2024-46780 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 683408258917541bdb294cd717c210a04381931e upstream. The superblock buffers of nilfs2 can not only be overwritten at runtime for modifications/repairs, but they are also regularly swapped, replaced during resizing, and even abandoned when degrading to one side due to backing device issues. So, accessing them requires mutual exclusion using the reader/writer semaphore "nilfs->ns_sem". Some sysfs attribute show methods read this superblock buffer without the necessary mutual exclusion, which can cause problems with pointer dereferencing and memory access, so fix it.
