Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound due to improper handling of the lcn variable on 32-bit platforms, where its size is insufficient to store values after a left shift operation. An attacker can cause data truncation or corruption by triggering operations that manipulate large logical cluster numbers.
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
