CVE-2017-17806 describes a kernel stack buffer overflow vulnerability in the Linux kernel's HMAC implementation (crypto/hmac.c) affecting versions before 4.14.8, specifically when using the AF_ALG-based hash interface and SHA-3. This flaw allows a local attacker to trigger the overflow through a crafted sequence of system calls due to a missing SHA-3 initialization. Rated 7.8 HIGH (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), it has a low attack complexity and requires local privileges, but can lead to high confidentiality, integrity, and availability impacts. There is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
