When an application extracts data into a bitset from a wide-character stream, internal stack memory allocation fails to properly account for character size and alignment. An attacker capable of supplying crafted input to an affected application could trigger a stack-based buffer overflow leading denial of service (DoS).","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-115455","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2562933","tags":[]},{"url":"https://gcc.gnu.org/cgit/gcc/commit/?id=5d419c69ce2e6b86d7da75f18736904885674219","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
