| Subject: CVE-2024-46781: nilfs2: fix missing cleanup on rollforward recovery error |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| nilfs2: fix missing cleanup on rollforward recovery error |
| |
| In an error injection test of a routine for mount-time recovery, KASAN |
| found a use-after-free bug. |
| |
| It turned out that if data recovery was performed using partial logs |
| created by dsync writes, but an error occurred before starting the log |
| writer to create a recovered checkpoint, the inodes whose data had been |
| recovered were left in the ns_dirty_files list of the nilfs object and |
| were not freed. |
| |
| Fix this issue by cleaning up inodes that have read the recovery data if |
| the recovery routine fails midway before the log writer starts. |
| |
| The Linux kernel CVE team has assigned CVE-2024-46781 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: |
