GHSA-GMCR-26HV-76C3

Vulnerability from github – Published: 2024-10-21 15:32 – Updated: 2024-10-23 18:33

Details

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. :)

Severity ?

7.8 (High)
