Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： drm/panel-edp：修复探针失败时的 i2c 适配器泄漏 请确保在探针失败（例如探针延迟）时释放 i2c 适配器的引用；如果设备树重复使用 'ddc-i2c-bus' 属性指向辅助 DDC 总线，也需在驱动解绑时释放该引用。
