Summary
ksmbd: add chann_lock to protect ksmbd_chann_list xarray
Details

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

ksmbd: add channlock to protect ksmbdchann_list xarray

ksmbdchannlist xarray lacks synchronization, allowing use-after-free in multi-channel sessions (between lookupchannlist() and ksmbdchanndel).

Adds rwsemaphore channlock to struct ksmbdsession and protects all xaload/xastore/xaerase accesses.
