Summary
In the Linux kernel, the following vulnerability has been resolved:
tee: fix NULL pointer dereference in tee_shm_put
tee_shm_put have NULL pointer dereference:
__optee_disable_shm_cache -->
shm = reg_pair_to_ptr(...);//shm maybe return NULL
tee_shm_free(shm); -->
tee_shm_put(shm);//crash
Add check in tee_shm_put to fix it.
