Description:
 crypto/pcrypt.c in the Linux kernel before 4.14.13 mishandles freeing
 instances, allowing a local user able to access the AF_ALG-based AEAD
 interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT)
 to cause a denial of service (kfree of an incorrect pointer) or possibly
 have unspecified other impact by executing a crafted sequence of system
 calls.
Ubuntu-Description:
 It was discovered that the parallel cryptography component of the Linux
 kernel incorrectly freed kernel memory. A local attacker could use this to
 cause a denial of service (system crash) or possibly execute arbitrary
 code.
