medium Tenable Cloud Security Plugin ID 459010

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: erofs: unify lcn as u64 for 32-bit
 platforms As sashiko reported [1], `lcn` was typed as `unsigned long` (or `unsigned int` sometimes), which
 is only 32 bits wide on 32-bit platforms, which causes `(lcn << lclusterbits)` to be truncated at 4 GiB.
 In order to consolidate the logic, just use `u64` consistently around the codebase. [1]
