| Subject: CVE-2024-49966: ocfs2: cancel dqi_sync_work before freeing oinfo |
| |
| Description |
| =========== |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-49966 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
