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.","published":"2026-05-26T17:16:54.000Z","lastModified":"2026-10-14T20:17:45.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-787"],"affected":["opensuse/libsolv","redhat/hardened images","redhat/openshift container platform","redhat/satellite","redhat/update infrastructure","redhat/enterprise linux"],"epss":{"score":0.00227,"percentile":0.13286,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.23%).
