CVE-2026-0915 is a high-severity vulnerability affecting GNU C Library versions 2.0 to 2.42, where calling getnetbyaddr or getnetbyaddr_r with a specific nsswitch.conf configuration and a zero-valued network query can leak stack contents to a DNS resolver. This vulnerability has a CVSS score of 7.5, indicating a high potential for impact due to its network-based attack vector and low attack complexity, leading to a high confidentiality impact. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion beyond a single mention.
