NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-vmware-6.12 package and not the linux-vmware-6.12 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

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.
