Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix lease break and ack state handling Do not skip valid lease states containing WRITE_CACHING when breaking level-II/read leases for writes and truncates. Handle lease break acknowledgments according to the SMB2 rule that the acknowledged state must be a subset of the server's break target. Apply the acknowledged state directly and keep the break pending on failed ACKs.
