In the Linux kernel, the following vulnerability has been resolved:
crypto: iaa - Fix potential use after free bug
The free_device_compression_mode(iaa_device, device_mode) function frees
"device_mode" but it iss passed to iaa_compression_modes[i]->free() a few
lines later resulting in a use after free.
The good news is that, so far as I can tell, nothing implements the
->free() function and the use after free happens in dead code. But, with
this fix, when something does implement it, we'll be ready. :)
