- Details
-
In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Validate the passed in fops for ibgetucaps()
Sashiko pointed out it is not safe to rely only on the devt because char/block alias so if the user finds a block device with the same dev_t it can masquerade as a ucap cdev fd.
Test the f_ops to only accept authentic cdevs.
