Red Hat Product Errata RHSA-2026:33231 - Security Advisory Issued: 2026-06-29 Updated: 2026-06-29 RHSA-2026:33231 - Security Advisory Overview Updated Packages Synopsis Moderate: glibc security, bug fix, and enhancement update Type/Severity Security Advisory: Moderate Red Hat Lightspeed patch analysis Identify and remediate systems affected by this advisory. View affected systems Topic An update for glibc is now available for Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. Description The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the name service cache daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Security Fix(es): glibc: glibc: Heap Buffer Overflow in `scanf` with `%mc` format specifier and large width (CVE-2026-5450) Bug Fix(es) and Enhancement(s): glibc: string/test-strncmp-nonarray failure on ppc64le (JIRA:RHEL-86477) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
