Search: CVE-2026-80489

CVE-2026-80489 is a medium severity vulnerability in the GNU C Library (glibc) versions 2.3 through 2.44. It involves an infinite loop condition when converting crafted EUC_JISX0213 input to UCS-4 or the internal wide character encoding, such as via iconv. The flaw occurs because the converter improperly handles certain two-code-point sequences when the output buffer is too small, causing the application to hang indefinitely. This affects only the EUC_JISX0213 character set, which is uncommon.
