| Subject: CVE-2022-49105: staging: wfx: fix an error handling in wfx_init_common() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| staging: wfx: fix an error handling in wfx_init_common() |
| |
| One error handler of wfx_init_common() return without calling |
| ieee80211_free_hw(hw), which may result in memory leak. And I add |
| one err label to unify the error handler, which is useful for the |
| subsequent changes. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49105 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: |
