What is CVE-2025-5915?

A vulnerability has been discovered in the Libarchive library that can lead to a heap buffer over-read. This occurs when the size of a filter block exceeds the limits imposed by the Lempel-Ziv-Storer-Schieber (LZSS) window. Consequently, this flaw may allow the library to read data beyond the allocated memory, which can trigger unpredictable behavior, cause program crashes, or expose sensitive information stored in adjacent memory regions.
