CVE-2015-3331

29
FAUCET Score

CVE-2015-3331 describes a buffer overflow vulnerability in the Linux kernel's AES-NI crypto driver (arch/x86/crypto/aesni-intel_glue.c) before version 3.19.3, affecting various Debian and Ubuntu Linux distributions. This flaw allows context-dependent attackers to trigger a denial of service (system crash) or potentially execute arbitrary code by manipulating memory locations during encrypted data processing. With a CVSS score of 9.3, it is considered critical due to its network-based attack vector, medium complexity, and complete impact on confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code, or Metasploit/Nuclei modules, and community discussion is minimal, with only one mention.
