[PATCH openEuler-1.0-LTS] i2c: img-scb: fix reference leak when pm_runtime_get_sync fails
by felix 06 Mar '24

06 Mar '24

From: Qinglang Miao <miaoqinglang(a)huawei.com> stable inclusion from stable-v5.10.37 commit e80ae8bde41266d3b8bf012460b6593851766006 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I94JR1 CVE: CVE-2020-36783 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 223125e37af8a641ea4a09747a6a52172fc4b903 ] The PM reference count is not expected to be incremented on return in functions img_i2c_xfer and img_i2c_init. However, pm_runtime_get_sync will increment the PM reference count even failed. Forgetting to putting operation will result in a reference leak here. Replace it with pm_runtime_resume_and_get to keep usage counter balanced.

[PATCH openEuler-1.0-LTS] nilfs2: fix potential use after free in nilfs_gccache_submit_read_data()

In nilfs_gccache_submit_read_data(), brelse(bh) is called to drop the reference count of bh when the call to nilfs_dat_translate() fails. If the reference count hits 0 and its owner page gets unlocked, bh may be freed. However, bh->b_page is dereferenced to put the page after that, which may result in a use-after-free bug. This patch moves the release operation after unlocking and putting the page. NOTE: The function in question is only called in GC, and in combination with current userland tools, address translation using DAT does not occur in that function, so the code path that causes this issue will not be executed. However, it is possible to run that code path by intentionally modifying the userland GC library or by calling the GC ioctl directly.
