- Summary
- [none]
- Details
-
crypto/algifskcipher.c in the Linux kernel before 4.4.2 does not verify that a setkey operation has been performed on an AFALG 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.
