| Subject: CVE-2022-48880: platform/surface: aggregator: Add missing call to ssam_request_sync_free() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| platform/surface: aggregator: Add missing call to ssam_request_sync_free() |
| |
| Although rare, ssam_request_sync_init() can fail. In that case, the |
| request should be freed via ssam_request_sync_free(). Currently it is |
| leaked instead. Fix this. |
| |
| The Linux kernel CVE team has assigned CVE-2022-48880 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: |
| https://git.kernel.org/stable/c/d2dc110deabe7142b60ebeed689e67f92795ee24 |
