| Subject: CVE-2025-22101: net: libwx: fix Tx L4 checksum |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: libwx: fix Tx L4 checksum |
| |
| The hardware only supports L4 checksum offload for TCP/UDP/SCTP protocol. |
| There was a bug to set Tx checksum flag for the other protocol that results |
| in Tx ring hang. Fix to compute software checksum for these packets. |
| |
| The Linux kernel CVE team has assigned CVE-2025-22101 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: |
