| Subject: CVE-2024-50176: remoteproc: k3-r5: Fix error handling when power-up failed |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| remoteproc: k3-r5: Fix error handling when power-up failed |
| |
| By simply bailing out, the driver was violating its rule and internal |
| assumptions that either both or no rproc should be initialized. E.g., |
| this could cause the first core to be available but not the second one, |
| leading to crashes on its shutdown later on while trying to dereference |
| that second instance. |
| |
| The Linux kernel CVE team has assigned CVE-2024-50176 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/87ab3af7447791d0c619610fd560bd804549e187 |
