CVE-2017-12192 (retired)

Priority
Description
The keyctl_read_key function in security/keys/keyctl.c in the Key
Management subcomponent in the Linux kernel before 4.13.5 does not properly
consider that a key may be possessed but negatively instantiated, which
allows local users to cause a denial of service (OOPS and system crash) via
a crafted KEYCTL_READ operation.
Ubuntu-Description
It was discovered that the key management subsystem in the Linux kernel did
not properly restrict key reads on negatively instantiated keys. A local
attacker could use this to cause a denial of service (system crash).
