In the Linux kernel, the following vulnerability has been resolved: ocfs2: cancel dqi_sync_work before freeing oinfo ocfs2_global_read_info() will initialize and schedule dqi_sync_work at the end, if error occurs after successfully reading global quota, it will trigger the following warning with CONFIG_DEBUG_OBJECTS_* enabled: ODEBUG: free active (active state 0) object: 00000000d8b0ce28 object type: timer_list hint: qsync_work_fn+0x0/0x16c This reports that there is an active delayed work when freeing oinfo in error handling, so cancel dqi_sync_work first. BTW, return status instead of -1 when .read_file_info fails. • https://git.kernel.org/stable/c/171bf93ce11f4c9929fdce6ce63df8da2f3c4475 https://git.kernel.org/stable/c/fc5cc716dfbdc5fd5f373ff3b51358174cf88bfc https://git.kernel.org/stable/c/89043e7ed63c7fc141e68ea5a79758ed24b6c699 https://git.kernel.org/stable/c/14114d8148db07e7946fb06b56a50cfa425e26c7 https://git.kernel.org/stable/c/4173d1277c00baeedaaca76783e98b8fd0e3c08d https://git.kernel.org/stable/c/bbf41277df8b33fbedf4750a9300c147e8f104eb https://git.kernel.org/stable/c/ef768020366f47d23f39c4f57bcb03af6d1e24b3 https://git.kernel.org/stable/c/a4346c04d055bf7e184c18a73dbd23b6a •

In the Linux kernel, the following vulnerability has been resolved: ocfs2: remove unreasonable unlock in ocfs2_read_blocks Patch series "Misc fixes for ocfs2_read_blocks", v5. This series contains 2 fixes for ocfs2_read_blocks(). The first patch fix the issue reported by syzbot, which detects bad unlock balance in ocfs2_read_blocks(). The second patch fixes an issue reported by Heming Zhao when reviewing above fix. This patch (of 2): There was a lock release before exiting, so remove the unreasonable unlock. • https://git.kernel.org/stable/c/6c150df9c2e80b5cf86f5a0d98beb7390ad63bfc https://git.kernel.org/stable/c/cf76c78595ca87548ca5e45c862ac9e0949c4687 https://git.kernel.org/stable/c/01f93d5e36753fc4d06ec67f05ce78c9c6f2dd56 https://git.kernel.org/stable/c/65cbd1279f4b999d56a838344a30642db24cd215 https://git.kernel.org/stable/c/97e1db17bc1ef4c2e1789bc9323c7be44fba53f8 https://git.kernel.org/stable/c/5245f109b4afb6595360d4c180d483a6d2009a59 https://git.kernel.org/stable/c/9753bcb17b36c9add9b32c61766ddf8d2d161911 https://git.kernel.org/stable/c/3f1ca6ba5452d53c598a45d21267a2c0c •

In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix memfd_pin_folios free_huge_pages leak memfd_pin_folios followed by unpin_folios fails to restore free_huge_pages if the pages were not already faulted in, because the folio refcount for pages created by memfd_alloc_folio never goes to 0. memfd_pin_folios needs another folio_put to undo the folio_try_get below: memfd_alloc_folio() alloc_hugetlb_folio_nodemask() dequeue_hugetlb_folio_nodemask() dequeue_hugetlb_folio_node_exact() folio_ref_unfreeze(folio, 1); ; adds 1 refcount folio_try_get() ; adds 1 refcount hugetlb_add_to_page_cache() ; adds 512 refcount (on x86) With the fix, after memfd_pin_folios + unpin_folios, the refcount for the (unfaulted) page is 512, which is correct, as the refcount for a faulted unpinned page is 513. • https://git.kernel.org/stable/c/89c1905d9c140372b7f50ef48f42378cf85d9bc5 https://git.kernel.org/stable/c/59e081ff2e91bbf19b8c1ecb75b031f778858383 https://git.kernel.org/stable/c/c56b6f3d801d7ec8965993342bdd9e2972b6cb8e •
