0 CVE-2026-89092 is a medium severity vulnerability in the GNU C Library (glibc) affecting versions from 2.3.4 up to but not including 2.45. It involves a stack overflow in the nscd service when a malicious DNS server returns an excessively large DNS response. This can cause nscd to crash, leading to degraded DNS resolution performance. Exploitation requires nscd to be enabled and configured to use an untrusted DNS server capable of sending large DNS records. The vulnerability does not cause denial of service but may corrupt nscd caches before crashing. The nscd service typically runs isolated with limited privileges, reducing risk of further compromise.
