CVE-2017-18075

Priority
Medium
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.
