What is CVE-2026-48864?

A heap buffer overflow vulnerability has been identified in libsolv that occurs during the handling of compressed data in .solv files. The flaw arises from inadequate input validation, allowing attackers to craft malicious .solv files. When these files are processed by applications using vulnerable versions of libsolv, they can lead to out-of-bounds memory access. Consequently, this can expose sensitive information, alter the normal execution flow of applications, or cause denial of service.
