CVE-2026-23226

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

ksmbd: add chann_lock to protect ksmbd_chann_list xarray

ksmbd_chann_list xarray lacks synchronization, allowing use-after-free in
multi-channel sessions (between lookup_chann_list() and ksmbd_chann_del).

Adds rw_semaphore chann_lock to struct ksmbd_session and protects
all xa_load/xa_store/xa_erase accesses.
