| Subject: CVE-2024-46768: hwmon: (hp-wmi-sensors) Check if WMI event data exists |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| hwmon: (hp-wmi-sensors) Check if WMI event data exists |
| |
| The BIOS can choose to return no event data in response to a |
| WMI event, so the ACPI object passed to the WMI notify handler |
| can be NULL. |
| |
| Check for such a situation and ignore the event in such a case. |
| |
| The Linux kernel CVE team has assigned CVE-2024-46768 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: |
