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.
