Description
In the Linux kernel, the following vulnerability has been resolved: HSI: ssi_protocol: Fix use after free vulnerability in ssi_protocol Driver Due to Race Condition In the ssi_protocol_probe() function, &ssi->work is bound with ssip_xmit_work(), In ssip_pn_setup(), the ssip_pn_xmit() function within the ssip_pn_ops structure is capable of starting the work. If we remove the module which will call ssi_protocol_remove() to make a cleanup, it will free ssi through kfree(ssi), while the work mentioned above will be used. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 \| ssip_xmit_work ssi_protocol_remove \| kfree(ssi); \| \| struct hsi_client *cl = ssi->cl; \| // use ssi Fix it by ensuring that the work is canceled before proceeding with the cleanup in ssi_protocol_remove().
