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.

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel 存在安全漏洞，该漏洞源于net:dsa:lantiq_gswip模块中发现使用后释放问题。在gswip_remove函数中，应该在释放mdiobus之前释放of_node_put(priv->ds->slave_mii_bus->dev.of_node)。
