This update for the Linux Kernel 4.4.90-6_12 fixes several issues.
The following security issue was fixed:
- CVE-2017-18075: crypto/pcrypt.c in the Linux kernel mishandled 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 (bsc#1077404).
Non security issue fixed:
- btrfs: account for pinned bytes in should_alloc_chunk (bsc#1077268)
