| Subject: CVE-2024-26717: HID: i2c-hid-of: fix NULL-deref on failed power up |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| HID: i2c-hid-of: fix NULL-deref on failed power up |
| |
| A while back the I2C HID implementation was split in an ACPI and OF |
| part, but the new OF driver never initialises the client pointer which |
| is dereferenced on power-up failures. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26717 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: |
