Summary

Details

A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within .solv files due to insufficient input validation. An attacker can provide a specially crafted .solv file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.

Severity

7.8 (High)

CVE-2026-48864 (GCVE-0-2026-48864)

Vulnerability from cvelistv5 – Published: 2026-05-26 16:16 – Updated: 2026-07-14 21:36

Title

Libsolv: heap buffer overflow in libsolv repopagestore via unchecked decompression of malicious .solv page data

Summary

A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.
