CVE-2026-5358 Detail

Description

The obsolete nis_local_principal function in the GNU C Library version 2.43 and older may overflow a buffer in the data section, which could allow an attacker to spoof a crafted response to a UDP request generated by this function and overwrite neighboring static data in the requesting application. NIS support is obsolete and has been deprecated in the GNU C Library since version 2.26 and is only maintained for legacy usage. Applications should port away from NIS to more modern identity and access management services.
