Overview

Affected versions of this package are vulnerable to Out-of-Bounds in the krb5_authenticate process. An attacker can cause arbitrary memory corruption or potentially execute code by sending a specially crafted SMB2 compounded request that triggers an out-of-bounds write in kernel heap memory.

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
