| Subject: CVE-2024-42299: fs/ntfs3: Update log->page_{mask,bits} if log->page_size changed |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| fs/ntfs3: Update log->page_{mask,bits} if log->page_size changed |
| |
| If an NTFS file system is mounted to another system with different |
| PAGE_SIZE from the original system, log->page_size will change in |
| log_replay(), but log->page_{mask,bits} don't change correspondingly. |
| This will cause a panic because "u32 bytes = log->page_size - page_off" |
| will get a negative value in the later read_log_page(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-42299 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: |
