| Subject: CVE-2022-48655: firmware: arm_scmi: Harden accesses to the reset domains |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| firmware: arm_scmi: Harden accesses to the reset domains |
| |
| Accessing reset domains descriptors by the index upon the SCMI drivers |
| requests through the SCMI reset operations interface can potentially |
| lead to out-of-bound violations if the SCMI driver misbehave. |
| |
| Add an internal consistency check before any such domains descriptors |
| accesses. |
| |
| The Linux kernel CVE team has assigned CVE-2022-48655 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: |
