| Subject: CVE-2025-23156: media: venus: hfi_parser: refactor hfi packet parsing logic |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: venus: hfi_parser: refactor hfi packet parsing logic |
| |
| words_count denotes the number of words in total payload, while data |
| points to payload of various property within it. When words_count |
| reaches last word, data can access memory beyond the total payload. This |
| can lead to OOB access. With this patch, the utility api for handling |
| individual properties now returns the size of data consumed. Accordingly |
| remaining bytes are calculated before parsing the payload, thereby |
| eliminates the OOB access possibilities. |
| |
| The Linux kernel CVE team has assigned CVE-2025-23156 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: |
