| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: wl1251: fix memory leak in wl1251_tx_work |
| |
| The skb dequeued from tx_queue is lost when wl1251_ps_elp_wakeup fails |
| with a -ETIMEDOUT error. Fix that by queueing the skb back to tx_queue. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37982 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: |
