| Subject: CVE-2025-22071: spufs: fix a leak in spufs_create_context() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| spufs: fix a leak in spufs_create_context() |
| |
| Leak fixes back in 2008 missed one case - if we are trying to set affinity |
| and spufs_mkdir() fails, we need to drop the reference to neighbor. |
| |
| The Linux kernel CVE team has assigned CVE-2025-22071 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: |
