Search: CVE-2026-77117

CVE-2026-77117 is a vulnerability in the GNU C Library (glibc) versions 2.3 through 2.44 involving an infinite loop during conversion of crafted SHIFT_JISX0213 input to UCS-4 or the internal wide character encoding. The issue arises when a SHIFT_JISX0213 sequence decodes to two code points but the output buffer only has room for the first, causing the converter to repeatedly emit a pending character without consuming further input, leading to application hang. This affects only the SHIFT_JISX0213 character set, which is uncommon.
