NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

Calling wordexp with WRDE_REUSE in conjunction with WRDE_APPEND in the GNU C Library version 2.0 to version 2.42 may cause the interface to return uninitialized memory in the we_wordv member, which on subsequent calls to wordfree may abort the process.
