CVE-2024-47732

Severity CVSS v4.0:
Pending analysis
Type:
CWE-416 Use After Free
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> crypto: iaa - Fix potential use after free bug<br /> <br /> The free_device_compression_mode(iaa_device, device_mode) function frees<br /> "device_mode" but it iss passed to iaa_compression_modes[i]-&gt;free() a few<br /> lines later resulting in a use after free.<br /> <br /> The good news is that, so far as I can tell, nothing implements the<br /> -&gt;free() function and the use after free happens in dead code. But, with<br /> this fix, when something does implement it, we&amp;#39;ll be ready. :)
