In order to save disk space and memory, as well as to make upgrading easier, common system code is kept in one place and shared between programs. This particular package contains the most important sets of shared libraries: the standard C library and the standard math library. Without these two libraries, a Linux system will not function. -------------------------------------------------------------------------------- Update Information: This update addresses two string function vulnerabilities specific to POWER10 machines (CVE-2025-5702, CVE-2025-5745) and fixes a bug in TLS management when auditors are used (rhbz#2330213). -------------------------------------------------------------------------------- ChangeLog: * Fri Jun 20 2025 Florian Weimer - 2.41-7 - Auto-sync with upstream branch release/2.41/master, commit 6e489c17f827317bcf8544efefa65f13b5a079dc: - ppc64le: Revert "powerpc: Optimized strcmp for power10" (CVE-2025-5702) - ppc64le: Revert "powerpc : Add optimized memchr for POWER10" (Bug 33059) - ppc64le: Revert "powerpc: Fix performance issues of strcmp power10" (CVE-2025-5702) - ppc64le: Revert "powerpc: Optimized strncmp for power10" (CVE-2025-5745) - elf: Keep using minimal malloc after early DTV resize (bug 32412) - nptl: Fix pthread_getattr_npwhen modules with execstack are allowed (BZ 32897) -------------------------------------------------------------------------------- References: [ 1 ] Bug #2330213 - ld.so calls realloc on a DTV which wasn't allocated with malloc https://bugzilla.redhat.com/show_bug.cgi?id=2330213 [ 2 ] Bug #2370507 - CVE-2025-5702 glibc: From CVEorg collector [fedora-42] https://bugzilla.redhat.com/show_bug.cgi?id=2370507 [ 3 ] Bug #2370512 - CVE-2025-5745 glibc: From CVEorg collector [fedora-42] https://bugzilla.redhat.com/show_bug.cgi?id=2370512 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
