| Subject: CVE-2024-42313: media: venus: fix use after free in vdec_close |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: venus: fix use after free in vdec_close |
| |
| There appears to be a possible use after free with vdec_close(). |
| The firmware will add buffer release work to the work queue through |
| HFI callbacks as a normal part of decoding. Randomly closing the |
| decoder device from userspace during normal decoding can incur |
| a read after free for inst. |
| |
| Fix it by cancelling the work in vdec_close. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42313 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: |
