CVE-2024-47732 Information

Description

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. :)
