| Subject: CVE-2024-49857: wifi: iwlwifi: mvm: set the cipher for secured NDP ranging |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: iwlwifi: mvm: set the cipher for secured NDP ranging |
| |
| The cipher pointer is not set, but is derefereced trying to set its |
| content, which leads to a NULL pointer dereference. |
| Fix it by pointing to the cipher parameter before dereferencing. |
| |
| The Linux kernel CVE team has assigned CVE-2024-49857 to this issue. |

| ========== |
| |
| 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: |
