[PATCH openEuler-22.03-LTS-SP1] jfs: fix array-index-out-of-bounds in dbAdjTree
by ZhaoLong Wang 22 Mar '24

22 Mar '24

From: Manas Ghandat <ghandatmanas(a)gmail.com> stable inclusion from stable-v5.10.210 commit 2037cb9d95f1741885f7daf50e8a028c4ade5317 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I96GQ3 CVE: CVE-2023-52601 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 74ecdda68242b174920fe7c6133a856fb7d8559b ] Currently there is a bound check missing in the dbAdjTree while accessing the dmt_stree. To add the required check added the bool is_ctl which is required to determine the size as suggest in the following commit. https://lore.kernel.org/linux-kernel-mentees/f9475918-2186-49b8-b801-6f0f9e… Reported-by: syzbot+39ba34a099ac2e9bd3cb(a)syzkaller.appspotmail.com Closes: https://syzkaller.appspot.com/bug?extid=39ba34a099ac2e9bd3cb Signed-off-by: Manas Ghandat <ghandatmanas(a)gmail.com> Signed-off-by: Dave Kleikamp <dave.kleikamp(a)oracle.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: ZhaoLong Wang <wangzhaolong1(a)huawei.com> --- fs/jfs/jfs_dmap.c | 60 ++++++++++++++++++++++++----------------------- 1 file changed, 31 insertions(+), 29 deletions(-) diff --git a/fs/jfs/jfs_dmap.c b/fs/jfs/jfs_dmap.c index 23e51992c964..6f42aed070dc 100644 --- a/fs/jfs/jfs_dmap.c +++ b/fs/jfs/jfs_dmap.c @@ -63,10 +63,10 @@ */ static void dbAllocBits(struct bmap * bmp, struct dmap * dp, s64 blkno, int nblocks);

[PATCH OLK-5.10] media: mtk-jpeg: Fix use after free bug due to error path handling in mtk_jpeg_dec_device_run

From: Zheng Wang <zyytlz.wz(a)163.com> stable inclusion from stable-v5.10.210 commit 43872f44eee6c6781fea1348b38885d8e78face9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I97NHC CVE: CVE-2023-52491 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 206c857dd17d4d026de85866f1b5f0969f2a109e ] In mtk_jpeg_probe, &jpeg->job_timeout_work is bound with mtk_jpeg_job_timeout_work. In mtk_jpeg_dec_device_run, if error happens in mtk_jpeg_set_dec_dst, it will finally start the worker while mark the job as finished by invoking v4l2_m2m_job_finish. There are two methods to trigger the bug. If we remove the module, it which will call mtk_jpeg_remove to make cleanup. The possible sequence is as follows, which will cause a use-after-free bug. CPU0 CPU1 mtk_jpeg_dec_... | start worker | |mtk_jpeg_job_timeout_work mtk_jpeg_remove | v4l2_m2m_release | kfree(m2m_dev); | | | v4l2_m2m_get_curr_priv | m2m_dev->curr_ctx //use If we close the file descriptor, which will call mtk_jpeg_release, it will have a similar sequence. Fix this bug by starting timeout worker only if started jpegdec worker successfully. Then v4l2_m2m_job_finish will only be called in either mtk_jpeg_job_timeout_work or mtk_jpeg_dec_device_run.
