| Subject: CVE-2024-49955: ACPI: battery: Fix possible crash when unregistering a battery hook |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ACPI: battery: Fix possible crash when unregistering a battery hook |
| |
| When a battery hook returns an error when adding a new battery, then |
| the battery hook is automatically unregistered. |
| However the battery hook provider cannot know that, so it will later |
| call battery_hook_unregister() on the already unregistered battery |
| hook, resulting in a crash. |
| |
| Fix this by using the list head to mark already unregistered battery |
| hooks as already being unregistered so that they can be ignored by |
| battery_hook_unregister(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-49955 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: |
