| Subject: CVE-2024-26927: ASoC: SOF: Add some bounds checking to firmware data |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: SOF: Add some bounds checking to firmware data |
| |
| Smatch complains about "head->full_size - head->header_size" can |
| underflow. To some extent, we're always going to have to trust the |
| firmware a bit. However, it's easy enough to add a check for negatives, |
| and let's add a upper bounds check as well. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26927 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/d133d67e7e724102d1e53009c4f88afaaf3e167c |
