| Subject: CVE-2024-32936: media: ti: j721e-csi2rx: Fix races while restarting DMA |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: ti: j721e-csi2rx: Fix races while restarting DMA |
| |
| After the frame is submitted to DMA, it may happen that the submitted |
| list is not updated soon enough, and the DMA callback is triggered |
| before that. |
| |
| This can lead to kernel crashes, so move everything in a single |
| lock/unlock section to prevent such races. |
| |
| The Linux kernel CVE team has assigned CVE-2024-32936 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/80a8b92950f8ee96582dba6187e3c2deca3569ea |
