| Subject: CVE-2022-49619: net: sfp: fix memory leak in sfp_probe() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: sfp: fix memory leak in sfp_probe() |
| |
| sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When |
| devm_add_action() fails, sfp is not freed, which leads to a memory leak. |
| |
| We should use devm_add_action_or_reset() instead of devm_add_action(). |
| |
| The Linux kernel CVE team has assigned CVE-2022-49619 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: |
