The KEYS subsystem in the Linux kernel before 4.4 allows local users to
gain privileges or cause a denial of service (BUG) via crafted keyctl
commands that negatively instantiate a key, related to
security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and
security/keys/user_defined.c.

Notes

Author Note
seth-arnold Debian’s triage suggested this was introduced by 146aa8b1453bd8f1ff2304ffb71b4ee0eb9acdcc
sbeattie verified this is an issue with precise’s kernel, the second reproducer in the git commit results in a NULL pointer exception
tyhicks As sbeattie mentioned above, this is present prior to 4.4. I’m setting the break commit to the start of git history which is after user keys were added
