| Subject: CVE-2024-36921: wifi: iwlwifi: mvm: guard against invalid STA ID on removal |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: iwlwifi: mvm: guard against invalid STA ID on removal |
| |
| Guard against invalid station IDs in iwl_mvm_mld_rm_sta_id as that would |
| result in out-of-bounds array accesses. This prevents issues should the |
| driver get into a bad state during error handling. |
| |
| The Linux kernel CVE team has assigned CVE-2024-36921 to this issue. |
| |
| |
| Affected and fixed versions |

| 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: |
