| Subject: CVE-2024-43860: remoteproc: imx_rproc: Skip over memory region when node value is NULL |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| remoteproc: imx_rproc: Skip over memory region when node value is NULL |
| |
| In imx_rproc_addr_init() "nph = of_count_phandle_with_args()" just counts |
| number of phandles. But phandles may be empty. So of_parse_phandle() in |
| the parsing loop (0 < a < nph) may return NULL which is later dereferenced. |
| Adjust this issue by adding NULL-return check. |
| |
| Found by Linux Verification Center (linuxtesting.org) with SVACE. |
| |
| [Fixed title to fit within the prescribed 70-75 charcters] |
| |
| The Linux kernel CVE team has assigned CVE-2024-43860 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: |
