In the Linux kernel, the following vulnerability has been resolved:
powerpc/mm: Fix null-pointer dereference in pgtable_cache_add
kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure. Ensure the allocation was successful
by checking the pointer validity.
A possible null-pointer dereference was found in pgtable_cache_add in the Linux kernel. This may cause a crash.
