| Subject: CVE-2024-58004: media: intel/ipu6: remove cpu latency qos request on error |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: intel/ipu6: remove cpu latency qos request on error |
| |
| Fix cpu latency qos list corruption like below. It happens when |
| we do not remove cpu latency request on error path and free |
| corresponding memory. |

| 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: |
