In the Linux kernel, the following vulnerability has been resolved:
zram: fix potential UAF of zram table
If zram_meta_alloc failed early, it frees allocated zram->table without setting it NULL. Which will potentially cause zram_meta_free to access the table if user reset an failed and uninitialized device.
