Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the ksmbd process due to a missing bounds check for the durable handle context. An attacker can access sensitive kernel memory and cause a denial of service by sending a specially crafted SMB2 CREATE request with a malformed durable-handle create context after authenticating with valid SMB credentials.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
