Description
The library preload list environment variable contains a list of libraries for the dynamic linker to load before loading the libraries required by the binary. If this list contains paths to libraries relative to the current working directory, unintended libraries may be preloaded. This variable is formatted as a space-separated list of libraries. Paths starting with a slash (/) are absolute paths.

Check Text ( C-27547r2_chk )
NOTE: The following must be done in the BASH shell Verify local initialization files have library preload list containing only absolute paths. # cut -d : -f 1 /etc/passwd \| xargs -n1 -IUSER sh -c 'grep -l LD_PRELOAD ~USER/.*' This variable is formatted as a colon-separated list of paths. If there is an empty entry, such as a leading or trailing colon, or two consecutive colons, this is a finding. If an entry begins with a character other than a slash (/) this is a relative path, and this is a finding.
