| Subject: CVE-2024-26637: wifi: ath11k: rely on mac80211 debugfs handling for vif |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: ath11k: rely on mac80211 debugfs handling for vif |
| |
| mac80211 started to delete debugfs entries in certain cases, causing a |
| ath11k to crash when it tried to delete the entries later. Fix this by |
| relying on mac80211 to delete the entries when appropriate and adding |
| them from the vif_add_debugfs handler. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26637 to this issue. |

| |
| The Linux kernel CVE team recommends that you update to the latest |

| 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: |
