CVE-2017-7374

Priority
High
Description
Use-after-free vulnerability in fs/crypto/ in the Linux kernel before
4.10.7 allows local users to cause a denial of service (NULL pointer
dereference) or possibly gain privileges by revoking keyring keys being
used for ext4, f2fs, or ubifs encryption, causing cryptographic transform
objects to be freed prematurely.
Ubuntu-Description
It was discovered that a use-after-free flaw existed in the filesystem
encryption subsystem in the Linux kernel. A local attacker could use this
to cause a denial of service (system crash).
