| Subject: CVE-2024-36032: Bluetooth: qca: fix info leak when fetching fw build id |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| Bluetooth: qca: fix info leak when fetching fw build id |
| |
| Add the missing sanity checks and move the 255-byte build-id buffer off |
| the stack to avoid leaking stack data through debugfs in case the |
| build-info reply is malformed. |
| |
| The Linux kernel CVE team has assigned CVE-2024-36032 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: |
