…cmp (bug 34683, CVE-2026-97399

CVE: CVE-2026-97399 (unknown) - powerpc: Fix one byte overread in strncasecmp (bug 34683, CVE-2026-97399): The Power8 strncasecmp (strcasecmp.S with USE_AS_STRNCASECMP) touches s1[n]/s2[n] in three places when the first n bytes compare equal and contain no NUL. A caller that maps exactly n readable bytes can get SIGSEGV if byte n falls on an unmapped page.
