| Subject: CVE-2025-21905: wifi: iwlwifi: limit printed string from FW file |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: iwlwifi: limit printed string from FW file |
| |
| There's no guarantee here that the file is always with a |
| NUL-termination, so reading the string may read beyond the |
| end of the TLV. If that's the last TLV in the file, it can |
| perhaps even read beyond the end of the file buffer. |
| |
| Fix that by limiting the print format to the size of the |
| buffer we have. |
| |
| The Linux kernel CVE team has assigned CVE-2025-21905 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: |
