CVE-2015-8970 (GCVE-0-2015-8970)

Vulnerability from cvelistv5 – Published: 2016-11-28 03:01 – Updated: 2024-08-06 08:36
VLAI
Summary
crypto/algif_skcipher.c in the Linux kernel before 4.4.2 does not verify that a setkey operation has been performed on an AF_ALG socket before an accept system call is processed, which allows local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted application that does not supply a key, related to the lrw_crypt function in crypto/lrw.c.
