Title
Use-after-free in parse_lease_state()
Summary
An out-of-bounds (OOB) memory read flaw was found in parse_lease_state in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. When an attacker sends the CREATE command with a malformed payload to KSMBD, due to a missing check of `NameOffset` in the `parse_lease_state()` function, the `create_context` object can access invalid memory.
Severity
7.1 (High)

Title
Linux: netback processing of zero-length transmit fragment
Summary
Transmit requests in Xen's virtual network protocol can consist of
multiple parts. While not really useful, except for the initial part
any of them may be of zero length, i.e. carry no data at all. Besides a
certain initial portion of the to be transferred data, these parts are
directly translated into what Linux calls SKB fragments. Such converted
request parts can, when for a particular SKB they are all of length
zero, lead to a de-reference of NULL in core networking code.
