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.
