ALSA-2026:96087: Moderate: glibc security update

Published Nov 9, 2026
·
Updated

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: nscd stack overflow leads to degraded DNS resolution (CVE-2026-89092) glibc: glibc DNS stub resolver: Denial of Service via long search domain in configuration (CVE-2026-8674) glibc: glibc: Privilege escalation and arbitrary code execution via TOCTOU race condition in dynamic loader (CVE-2026-86805) glibc: glibc: Local attacker can cause denial of service and information disclosure via stack-based buffer overflow. (CVE-2026-95818)

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.

Frequently Asked Questions

1

Which systems are most exposed to the DNS-related issues?

Systems using glibc's DNS stub resolver may be exposed to denial of service if their configuration contains a long search domain. Systems running nscd may also be affected by the stack overflow that degrades DNS resolution.

2

Does exploitation require local access for every issue in this update?

No. The update describes a local attacker requirement for the stack-based buffer overflow that can cause denial of service and information disclosure. It also identifies a dynamic-loader TOCTOU race condition that can lead to privilege escalation and arbitrary code execution, while the DNS issues are described in terms of resolver or nscd behavior rather than an explicit local-access requirement.

3

Which installed packages should be reviewed when applying this update?

Review installed glibc packages, including glibc, glibc-common, glibc-devel, glibc-all-langpacks, glibc-gconv-extra, glibc-doc, glibc-benchtests, and compat-libpthread-nonshared. These libraries are used by multiple programs and are required for normal Linux system operation.
