| Subject: CVE-2023-52459: media: v4l: async: Fix duplicated list deletion |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: v4l: async: Fix duplicated list deletion |
| |
| The list deletion call dropped here is already called from the |
| helper function in the line before. Having a second list_del() |
| call results in either a warning (with CONFIG_DEBUG_LIST=y): |
| |
| list_del corruption, c46c8198->next is LIST_POISON1 (00000100) |
| |
| If CONFIG_DEBUG_LIST is disabled the operation results in a |
| kernel error due to NULL pointer dereference. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52459 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: |
| https://git.kernel.org/stable/c/b7062628caeaec90e8f691ebab2d70f31b7b6b91 |
