What is CVE-2025-52886?

The Poppler PDF rendering library contains a vulnerability due to the use of std::atomic_int for reference counting, limited to 32 bits. This can lead to an overflow of the reference count, causing a use-after-free condition. This issue potentially exposes systems to exploitation, allowing malicious actors to execute arbitrary code or cause denial of service. Poppler version 25.06.0 addresses this flaw, ensuring safer reference counting practices.
