CVE-2025-52886

Poppler Use After Free Vulnerability

CVSS 5.5 MEDIUMEPSS 0.4%CWE-416
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.
