| Subject: CVE-2024-56572: media: platform: allegro-dvt: Fix possible memory leak in allocate_buffers_internal() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: platform: allegro-dvt: Fix possible memory leak in allocate_buffers_internal() |
| |
| The buffer in the loop should be released under the exception path, |
| otherwise there may be a memory leak here. |
| |
| To mitigate this, free the buffer when allegro_alloc_buffer fails. |
| |
| The Linux kernel CVE team has assigned CVE-2024-56572 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: |
