MediumCVSS 5.5/10Last modified Oct 19, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

smb: server: split ksmbd_rdma_stop_listening() out of ksmbd_rdma_destroy()

We can't call destroy_workqueue(smb_direct_wq); before stop_sessions()!

Otherwise already existing connections try to use smb_direct_wq as a NULL pointer.
