| Subject: CVE-2025-23158: media: venus: hfi: add check to handle incorrect queue size |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: venus: hfi: add check to handle incorrect queue size |
| |
| qsize represents size of shared queued between driver and video |
| firmware. Firmware can modify this value to an invalid large value. In |
| such situation, empty_space will be bigger than the space actually |
| available. Since new_wr_idx is not checked, so the following code will |
| result in an OOB write. |
| ... |
| qsize = qhdr->q_size |
| |
| if (wr_idx >= rd_idx) |
| empty_space = qsize - (wr_idx - rd_idx) |
| .... |
| if (new_wr_idx < qsize) { |
| memcpy(wr_ptr, packet, dwords << 2) --> OOB write |
| |
| Add check to ensure qsize is within the allocated size while |
| reading and writing packets into the queue. |
| |
| The Linux kernel CVE team has assigned CVE-2025-23158 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: |
