| Subject: CVE-2022-49757: EDAC/highbank: Fix memory leak in highbank_mc_probe() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| EDAC/highbank: Fix memory leak in highbank_mc_probe() |
| |
| When devres_open_group() fails, it returns -ENOMEM without freeing memory |
| allocated by edac_mc_alloc(). |
| |
| Call edac_mc_free() on the error handling path to avoid a memory leak. |

| 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: |
