[PATCH OLK-5.10] nilfs2: fix potential use after free in nilfs_gccache_submit_read_data()
by ZhaoLong Wang 07 Mar '24

07 Mar '24

From: Pan Bian <bianpan2016(a)163.com> stable inclusion from stable-v5.10.198 commit 7130a87ca32396eb9bf48b71a2d42259ae44c6c7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I95AT5 CVE: CVE-2023-52566 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 7ee29facd8a9c5a26079148e36bcf07141b3a6bc upstream. 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.

[PATCH openEuler-1.0-LTS 1/2] nvme-loop: don't put ctrl on nvme_init_ctrl error
by Li Nan 06 Mar '24

From: Chaitanya Kulkarni <chaitanya.kulkarni(a)wdc.com> mainline inclusion from mainline-v5.10-rc1 commit 1401fcc4e3da97c44dcc7cbf538c07e24768d791 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I956G7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The function nvme_init_ctrl() gets the ctrl reference & when it fails it does put the ctrl reference in the error unwind code. When creating loop ctrl in nvme_loop_create_ctrl() if nvme_init_ctrl() returns non zero (i.e. error) value it jumps to the "out_put_ctrl" label which calls nvme_put_ctrl(), that will lead to douple ctrl put in error unwind path. Update nvme_loop_create_ctrl() such that this patch removes the "out_put_ctrl" label, add a new "out" label after nvme_put_ctrl() in error unwind path and jump to newly added label when nvme_init_ctrl() call retuns an error.
