libsolv: A flaw was found in libsolv
CVE-2026-48864 is fixed in 15 products on 1 platform, first by ALAS2023-2026-1798, released June 8, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
