Description OSIDB Bzimport 2024-09-11 16:21:28 UTC 
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.
