In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
ksmbd: retain connection for pending notify work<\/p>\n
Deferred CHANGE_NOTIFY work keeps an async message ID after the original
\nrequest work is released. A durable handle can outlive its connection, so
\nthe connection teardown can destroy its async IDA before the handle close
\nreleases the pending notify work.<\/p>\n
Give the synthetic deferred work a connection reference. Release it after
\nthe async ID in ksmbd_free_work_struct(). This keeps the async IDA alive
\nuntil the deferred work is released, even when the original connection has
\nalready left the connection list.<\/p>\n
During server shutdown there is no client to receive a cleanup response.
\nSkip the write and only release the pending work.<\/p>\n","protected":false},"excerpt":{"rendered":"
