CVE-2025-5745 is a medium-severity vulnerability affecting the GNU C Library (glibc) version 2.40 and later, specifically its strncmp implementation optimized for Power10 processors. This flaw involves the function overwriting non-volatile vector registers (v20-v31) without saving their contents, which can lead to altered program control flow or information leakage of input strings. With a CVSS score of 5.6, the vulnerability has a network attack vector and high attack complexity, potentially resulting in low impact to confidentiality, integrity, and availability. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
