- Summary
- tee: fix register_shm_helper()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
tee: fix register_shm_helper()
In register_shm_helper(), fix incorrect error handling for a call to iov_iter_extract_pages(). A case is missing for when iov_iter_extract_pages() 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(TEE_IOC_SHM_REGISTER) where parts of the buffer isn't mapped.
