In the Linux kernel, the following vulnerability has been resolved: mmc: mmc_test: Fix NULL dereference on allocation failure If the "test->highmem = alloc_pages()" allocation fails then calling __free_pages(test->highmem) will result in a NULL dereference. Also change the error code to -ENOMEM instead of returning success.
