Improper handling of consecutive end-of-file newline markers can corrupt internal hunk (single block of changes in diff) data structures, causing the application to pass a NULL pointer to fwrite() during patch processing.\nAn attacker can trigger this condition with a malicious patch file, causing the utility to crash and resulting in a denial of service.\n\n\n\nThis issue has been fixed in the commit e6d6a4e021660679d7fc9150f981d4920f722313","id":"ALPINE-CVE-2026-56288","modified":"2026-11-05T01:30:03.027044008Z","published":"2026-07-09T11:16:40.713Z","references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-56288"}],"schema_version":"1.9.2","severity":[{"score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","type":"CVSS_V3"}],"upstream":["CVE-2026-56288"]}
