| Subject: CVE-2023-52495: soc: qcom: pmic_glink_altmode: fix port sanity check |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| soc: qcom: pmic_glink_altmode: fix port sanity check |
| |
| The PMIC GLINK altmode driver currently supports at most two ports. |
| |
| Fix the incomplete port sanity check on notifications to avoid |
| accessing and corrupting memory beyond the port array if we ever get a |
| notification for an unsupported port. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52495 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: |
