| Source |
|
| Severity | Medium |
| Remote | No |
| Type | Denial of service |
| Description | The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8, 4.9.71, 4.4.107, 3.18.89, 3.16.52 and 3.2.97 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization. |
