| Subject: CVE-2025-21665: filemap: avoid truncating 64-bit offset to 32 bits |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| filemap: avoid truncating 64-bit offset to 32 bits |
| |
| On 32-bit kernels, folio_seek_hole_data() was inadvertently truncating a |
| 64-bit value to 32 bits, leading to a possible infinite loop when writing |
| to an xfs filesystem. |
| |
| The Linux kernel CVE team has assigned CVE-2025-21665 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: |
