CVE-2026-23226
Description
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.
