| Subject: CVE-2025-37755: net: libwx: handle page_pool_dev_alloc_pages error |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: libwx: handle page_pool_dev_alloc_pages error |
| |
| page_pool_dev_alloc_pages could return NULL. There was a WARN_ON(!page) |
| but it would still proceed to use the NULL pointer and then crash. |
| |
| This is similar to commit 001ba0902046 |
| ("net: fec: handle page_pool_dev_alloc_pages error"). |
| |
| This is found by our static analysis tool KNighter. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37755 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: |
