- Summary
- tee: fix register_shm_helper()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
tee: fix registershmhelper()
In registershmhelper(), fix incorrect error handling for a call to ioviterextractpages(). A case is missing for when ioviterextractpages() only got some pages and return a number larger than 0, but not the requested amount.
This fixes a possible NULL pointer dereference following a bad input from ioctl(TEEIOCSHM_REGISTER) where parts of the buffer isn't mapped.
