| Subject: CVE-2023-52918: media: pci: cx23885: check cx23885_vdev_init() return |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: pci: cx23885: check cx23885_vdev_init() return |
| |
| cx23885_vdev_init() can return a NULL pointer, but that pointer |
| is used in the next line without a check. |
| |
| Add a NULL pointer check and go to the error unwind if it is NULL. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52918 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: |
