| Subject: CVE-2024-58080: clk: qcom: dispcc-sm6350: Add missing parent_map for a clock |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| clk: qcom: dispcc-sm6350: Add missing parent_map for a clock |
| |
| If a clk_rcg2 has a parent, it should also have parent_map defined, |
| otherwise we'll get a NULL pointer dereference when calling clk_set_rate |
| like the following: |
| |
| [ 3.388105] Call trace: |
| [ 3.390664] qcom_find_src_index+0x3c/0x70 (P) |
| [ 3.395301] qcom_find_src_index+0x1c/0x70 (L) |
| [ 3.399934] _freq_tbl_determine_rate+0x48/0x100 |
| [ 3.404753] clk_rcg2_determine_rate+0x1c/0x28 |
| [ 3.409387] clk_core_determine_round_nolock+0x58/0xe4 |
| [ 3.421414] clk_core_round_rate_nolock+0x48/0xfc |
| [ 3.432974] clk_core_round_rate_nolock+0xd0/0xfc |
| [ 3.444483] clk_core_set_rate_nolock+0x8c/0x300 |
| [ 3.455886] clk_set_rate+0x38/0x14c |
| |
| Add the parent_map property for the clock where it's missing and also |
| un-inline the parent_data as well to keep the matching parent_map and |
| parent_data together. |
| |
| The Linux kernel CVE team has assigned CVE-2024-58080 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: |
