Описание
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.
A use-after-free flaw was found in the Linux kernel's file system encryption implementation. A local user could revoke keyring keys being used for ext4, f2fs, or ubifs encryption, causing a denial of service on the system.
Отчет
This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6, 7 and MRG-2 as the code where the flaw was found is not present in these products.
