Ubuntu update for linux-aws

Exploit availability: No

Description

The vulnerability allows a remote user to read data or crash the application.

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.

Mitigation

Update the affected package linux-aws to the latest version.
