CVE-2015-3331

HIGH 9.3EPSS 10.0%

Does this matter?

EPSS puts the probability of exploitation in the next 30 days at 10.0%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.

Description

The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before 3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an AF_ALG(aead) socket.

EPSS trend

EPSS 10.0% since 4 November 2026; no change recorded yet. The dashed line is the ten per cent mark our analysts treat as “patch before the next change window”. Points are recorded when the score first appears and whenever it moves by a percentage point or more.
