| Subject: CVE-2023-52853: hid: cp2112: Fix duplicate workqueue initialization |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| hid: cp2112: Fix duplicate workqueue initialization |
| |
| Previously the cp2112 driver called INIT_DELAYED_WORK within |
| cp2112_gpio_irq_startup, resulting in duplicate initilizations of the |
| workqueue on subsequent IRQ startups following an initial request. This |
| resulted in a warning in set_work_data in workqueue.c, as well as a rare |
| NULL dereference within process_one_work in workqueue.c. |
| |
| Initialize the workqueue within _probe instead. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52853 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: |
