The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream poppler package and not the poppler package as distributed by RHEL.
Poppler is a PDF rendering library. Versions prior to 25.06.0 use std::atomic_int for reference counting. Because std::atomic_int is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue.
