The printf builtin reserves four bytes before converting a Unicode \\u or \\U escape, but the multi-byte token can need five or six bytes. A local user who can supply such an escape to dash printf or echo %b, including through dash -c and a positional argument, can write one or two bytes past that reservation.","cvssScore":4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-102474","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2543004","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
