In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
smb\/server: abort initialization when proc setup fails<\/p>\n
ksmbd_server_init() calls ksmbd_proc_init() before creating the
\nremaining proc entries and server subsystems. ksmbd_proc_init() tears
\ndown partial state on a procfs or percpu_counter allocation failure,
\nbut returns void, so ksmbd_server_init() continues as if the counters
\nwere usable.<\/p>\n
Once userspace starts the server, server_ctrl_handle_init() calls
\nksmbd_proc_reset(), which reaches percpu_counter_set() with a NULL
\nper-CPU counters pointer on SMP systems. The later ksmbd_proc_create()
\ncalls also receive a NULL parent and may create entries in the \/proc
\nroot; ksmbd_proc_cleanup() cannot remove those entries because
\nksmbd_proc_fs is NULL.<\/p>\n","protected":false},"excerpt":{"rendered":"
