CVE-2024-47732: crypto: iaa - Fix potential use after free bug
In the Linux kernel, the following vulnerability has been resolved:
crypto: iaa - Fix potential use after free bug
The freedevicecompressionmode(iaadevice, devicemode) function frees "devicemode" but it iss passed to iaacompressionmodes[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. :)
